Man, I don't even know where to start. This is going to sound like such a troll question. If people could give me some reassurance or tell me whether or not I'm overreacting or anything like that, I'll be happy. I'm just out of options and I feel like Reddit might have a few people that are involved with some of the stuff I mention in this question and could give me an opinion from their side? That'd be cool.

Throwaway cause my boyfriend uses Reddit. I don't know if he follows this subreddit but, whatever.

I've been with "Timothy" for nearly 8 months now. Well, things have been going fine, apart from one thing, which is now starting to really kill the mood.

Timothy is very much in the belief that modern day political correctness and Feminism is 'ruining society'. He follows all the anti-sjw Youtubers you could imagine (I can only remember a few; The Amazing Atheist, Thunderf00t, TL;DR, Sargon of Akaad) and watches their videos religiously. He'll drop everything we're doing to watch a video from one of them and he's checking youtube every few hours just to see if they have a video up. I'm pretty sure he's also part of a few subreddits on the subject.

Now, this, I wouldn't have a problem with at all. I mean, like whatever videos you like, it's none of my business. I mean apart from one of the guys he watches having the most pretentious voice I've ever heard, it doesn't bother me.

The problem is that he rants about this shit to me for HOURS. He'll turn the topic of a normal conversation onto something he saw on a video from one of the above YouTubers not even a minute in. When I tell him I I don't really keep up to date with any social justice affairs, he'll go right back to the beginning of the situation in question and explain it all, very judgementally, then get back to his rant. He'll also often tell me about the same thing twice, and I'll say "I know, you told me this the other day." but he'll carry on almost as if he didn't hear me.

This is happening more and more regularly, to the point where he'll just bring it up out of the blue when something so much as tickles the subject lightly. For instance, the other day we went shopping and I saw some really nice coloured hair dye. I pointed it out and said how I wished I was brave enough to have hair like that, and he just said "Ahh, the 'Tumbelerina' (sp?) hair dye!" and went off again.

Recently I've been telling him often that I'm sorry but I'm really not interested in that stuff enough for me to understand, I can't contribute to the conversation other than the occasional "Oh, I see" "Really?" or "Wow" and, this being the emphasis, I'd be grateful if he didn't turn nearly EVERY conversation we have (some very meaningful and serious) into an Anti PC rant, but he just said "I don't turn EVERY conversation into a rant!" and started acting really offended and telling me I shouldn't try to police his opinions and ended it there.

I just don't know what to do anymore. God knows I love this guy but I'm starting to get silently angry at him whenever he goes off about radfems or BLM activists or whatever the topic of the day is for him. I don't want him to think I don't want him to be able to talk about it (after all, he's very passionate about Free Speech and all that, and I agree its important), I just would really rather not hear this shit for hours every damn time I'm with him.

Any tips? It's starting to make me think he's developed an unhealthy obsession with this stuff, but am I overreacting here? If so, how can I calm down and deal with this?

I don't mind him watching the videos and I'm not asking him to ignore it or to suddenly identify as a feminist or anything like that, I don't want him to stop talking about it with me occasionally either but I just want him to understand that I'd like it to stop overshadowing nearly all conversations we have, because it's seriously starting to bore me and make me angry at him and therefore less affectionate towards him.

TL;DR (ha) - My boyfriend keeps going on about anti-sjw stuff every chance he can get and is showing no signs of stopping despite me trying to tell him it's becoming a problem. I'm losing my mind.
