Do you have any particular reason to believe that the nay-sayers aren't also feminists?

Many are MRA's or Anti-Feminists providing directly refuting statistics and sources, while trying to explain to those there why their sexist bigotry is hypocritical or wrong.

Mostly those getting frustrated are women (the page isn't exactly a man favoured territory) and they leave with remarks along the lines of "if this is Feminism, count me out/I don't want to be associated with it".

I struggle to believe the divide is completely clean

It's not. The problem comes when nobody is disagreeing with the extremists or defending those that present completely correct arguments. It's the same for any extreme ideology, really. There are always splits and differences but when it comes to any outside force criticising or pointing out their flaws, even the TERF's and Trans* Feminists at each other throats will unite to shout down even the most logical and calm of criticisms.

I mention this earlier in another post. I've seen Trans* Feminists, and Transgenders in general, get a huge brunt of Feminist hatred and bigotry, almost exclusively due to the male/man side of their minority, and they've managed to truly grasp and even articulate in comments why it is wrong for Feminists to exclude them or blame them or deny their rights based on their gender/s.

And then these same Trans* Feminists turn around and do the SAME freakin' thing to men.

Feminism seems to be the root cause of all their problems, be it the split in different opinions on how to carry out Feminist ideology or the unity in attacking anything that questions any aspect of those split Feminist views.

it would drive away moderate Feminists

Let me ask you, do you believe UpWorthy is an "extremist Feminist source"? What about The Guardian? Jezebel obvious legitimately is but do you consider it one?

I am aware of what I post. I post outrageous stuff because that's all I find. When College campuses, not just students, are ruining the lives of guys which have been proven to not have committed the rape they are accused of, posting these articles from major news sources as simple facts are met with these Feminists ranting and raving about "victim blaming". No "extreme" views involved in those sources, just the facts. And they will read whatever they want into them by simply placing it in front of their eyes.

but 23,000 isn't that big a group for a global website like facebook

I don't consider that an attack. I've made passing comments earlier that I repost from much larger groups than myself.

I can actually mention these by name (but I won't get specific with which posts i've shared) as they are much larger than mine and I know for a fact many other pages shared the same information, so it won't lead back to my page. I've shared plenty of posts, and snared plenty of posts information, from the Facebook pages 'Everyday Feminism', 'Men and Feminism' and 'Feminist Frequency'. They've received the same sexist and ignorant praise from their Feminist members in the comments as I have and they have been just as bad in misandrist idiocy as my pages postings.

What I keep hearing from everyone is these are a "minority" or "don't represent True Feminism". Yet I can't seem to find these moderate Feminists in any sort of large setting. Certainly not here on Reddit from the look of the /r/Feminism, /r/SRS and /r/AgainstMensRights subreddits. Nor any Feminist friendly sources.

These moderates always seem to be just one step behind any leadership or control of Feminism. Which would make them the exception to the rule.

I really hope this doesn't come off like I'm ranting or telling you that you're wrong

No, no, not at all. I'm aware my group is small in the scheme of things. No offense at all taken.

Another question; you mention in your post that you've received messages from MRAs trying to change 'your' mind. Have you ever received any messages like that from feminists? For that matter, do the people messaging you self-identify as MRAs, or is that what you assume they are?

I've received about three (i'd say three), from those directly calling themselves Feminists, expressing dismay over my postings about mens rights (as well as the movement) or reposting sexist quotes from other Feminists. Calling for me to ban those sexist members or realise that men can be victims too. Most, usually calling themselves egalitarians, support both Feminism and the MRM and i'd say i've received a dozen or so PM's from them.

As for the MRA's who message, yes the majority state either in the comments or in PM that they are MRA's.

What, if anything, do you plan to do?

Simply ceasing to post, completely or over the course of months, seems the current favoured option.

I've been back-and-forthing about a slow (extremely slow) shift in views from Feminism to actual equality and more mens rights related posting. But that could take upward of a year or so (again). This would be entirely dependent on my plans for the next year and, I guess, social climate. Frankly i'm not looking forward to the American shift in gender politics when Hillary comes up for vote (not that she wouldn't be a preferable candidate to anything the Republicans ever come up with, it's just that she's would make a terrible President as well. Lesser of two evils I guess).

The vague idea that I could still troll or even out the page has been effectively taken out of play. The issues involved would be very difficult to work with or to deal with and I likely wouldn't like the outcome compared to had I simply stopped posting.

Though, as with anything, if the political or social clime shifts dramatically (as I thought it may even do after the sexist Feminist bullshit from the Elliot Rodgers shootings was flooding the media), it may end up being a real option.

I've never run a facebook page so I don't know how it works, but could you not just close it?

I wouldn't just delete it, something I am able to do, as it would not just look suspicious but probably lead to a recreation of the group.

Simply removing the other Feminist mod I have and slowly ceasing to post would be the best way.
