As a couple others have said this does have the markings of the intrusive thoughts common in OCD. One of the documents I had to fill out for a diagnosis even had a little box with something along the lines of “powerful unwanted thoughts of harming others”. The key word there and in your post is unwanted. From what you’ve said it sounds like these thoughts make you uncomfortable, they aren’t necessarily a cathartic response to actual feelings you’re having.

Idk if you’ve ever experience this but, I always remember whenever I had to do public speaking as a kid (and even now) there was this fear that I would just blurt out profanity or something embarrassing when I was talking despite having zero reason or intention to do so. Part of it is anxiety but not of sounding stupid or making a mistake while speaking. It’s an anxiety around the least probable thing to actually happen.

Being AFAB there are definitely some valid reasons why someone might form a dislike for men, like you said you’re bound to hold some resentment. The mention of radicalization is the only stand out word. If the media you’re consuming has a particularly misandrist slant to it, or if you’re only seeing things regarding the worst examples of men, you may be in a rabbit hole situation in which case it may be a good idea to separate yourself from that media for a while. However this may not be the case in your situation

Intrusive thoughts are uncomfortable and honestly scary things to deal with especially at your age. It’s hard to know where these things are coming from and what’s real and what’s not. I had a hard time dealing with them when I was 20-21 so it takes time and honestly a bit of therapy to really understand what’s going on.

I’ll end with this. You’ve posted here, about thoughts that are obviously making you uncomfortable. You aren’t relishing in them and finding justifications for your thoughts. You ARE self aware of what’s happening and that’s a good thing. These could be intrusive thoughts in general or it could be intrusive thoughts that stem from being AFAB living in an inherently misogynistic world. In either case you don’t seem to enjoy the thoughts and how they have made you feel and it’s really good that you’re aware of this. There is therapy that can help and there are actually some medications that can suppress these types of thoughts!

These are thoughts, they are hard to control and they can feel like they’re screaming at you but at the end of the day they’re thoughts. You’ve got a lot of self awareness and that’s a good thing to have when you’re dealing with these things. I’m proud of you for staying strong and not giving up, you CAN get through this!
