This is a big reason why inceldom has risen imo. Not because of the content, but because of groups of men all reinforcing this behavior.
Now, I won't lie, roleplay or imagination is one thing, but going online and normalizing this behavior in public is a very very different. Thing, and changes and normalizes that it's okay to do around real women. Thoughts and behaviors change, and then they wonder why real actual women want nothing to do with them.
In essence, hey if impregnation is your kink, you do you. You talk that way in public? Pretty weird bro.
