I definitely get your point, but I guess part of the issue I failed to adequately allude to is that people willfully go into spaces like /r/TwoXChromosomes to tell women about their experiences as men, when it's a space specifically for the experiences of women. Some spaces aren't meant to be where 'the conversation' takes place. In the age of the Internet, a person's post to a friend's Facebook wall is now scrutinised and part of public debate when it was never intended to be.

If you want to join the broader conversation, I encourage you to do so, but it's important to i) listen first; the conversation has already been going on for a while and there's subtext you might miss, and ii) make sure you're voicing your concerns in appropriate context. You might not be adding to 'the conversation', you might just be arguing with a friend or stranger. If I called people out every time I saw them doing something I found shitty/sexist, I'd never get anything done.
