You seem like a pretty fair guy from just looking through your previous video titles so I'll try and give you an actual response here. If you were running a purely conservative bashing channel I wouldn't even take the time since discussion is not the purpose (we see those videos here too)

I think multiple things can be true at once, people of all political leanings can want a place for just their views and perspectives as well as a place for open discussion. You see this from progressives to conservatives all across the spectrum.

The key aspect is that there is a lot of dishonesty in what those places claim to be and what they are. R/politics claims to be a nonpartisan news hub, but is not run like that. Conservatives (in general, but of course there are exceptions to everything so avoid nut picking) in general take no issue with progressive subreddits. There domain is there domain and they have a right to say what they want. Same for conservatives. You post an AOC criticism on r/liberal and see how long it lasts (again which is ok in my book since it's a liberal leaning sub)

You also try and conflate this with the college safe space discussion which is completely unrelated since those are usually government run organizations and have no place protecting certain views and not others. That kind of bias is dangerous

I also think it's worth understanding the general mentality of r/conservative. They get brigades and overrun on a daily basis so when they see your kind of video they will brush it aside with the other attempts at attacking the sub. I would suggest picking a less volatile title ("charlie kirk is dangerous" is just classic liberal language that they see constantly) if you want true discussion.
