once-progressive boyfriend turned socially conservative/traditional : QAnonCasualties

Hi, so long story short my boyfriend and I have been together for 6 years now. When we first started dating he was pretty progressive and he even went to pride parades with me, said he was really disappointed after Roe v Wade was overturned, etc. But in the past 1.5 or so years he really started falling into the “traditional” beliefs, became a lot more Catholic, and socially conservative. We've had a lot of big disagreements in the last year, starting with the Barbie movie last summer…..he has made condescending comments about “woke leftists”, the “west is losing their morals”, etc. Then recently I saw on Instagram reels (I just happened to come across posts he's liked), that he's liked reels that were making fun of pronouns and then one about how couples with kids without a mom are “unnatural”. He also liked one about how modern feminism is destroying society. I am seriously appalled that he has these views and I'm so dissappointed. He doesn't voice it to me because he knows how upset and defensive I get, but now I know what he actually thinks. I just have a feeling he's listening to those podcasts about being “alpha males”, the need for women to have kids, importance of Christianity in society….etc. Anyway obviously it seems like the answer is pretty clear here, but is it possible for a person like this to be convinced otherwise? Could he drop these beliefs? It's just hard because he used to be a different person..and we've been together for so long, we live together, so much is tied up. But it seems like for the most part people who go down this route only go deeper in it. It's not too dramatic of a reason to break up with someone, right? Each time I've brought it up he's said I'm being too controlling about his views and we should agree to disagree. He says I'm being a “militant leftist who doesn't have room for other views”……I can't handle being with someone who has such disrespectful views and I'm just wondering what went wrong..and when…and also, I just hate what Instagram reels, TikTok, and these certain male influencers have done lately. It's bizarre to see so many guys turn right wing in the past year

The are onto you, being Catholic is a Q-adjacent ideology.
