The issue is that is neither common nor a natural thing for men to "struggle not to rape someone" as much as you think it is. While your intentions might be good, and I do believe that, it reads like some sort of freudian slip.
Imagine if someone wrote "hey guys, let's be honest, I don't really like this thing of urinating on your food before eating, can we just agree to stop doing that :)".
You wouldn't think "oh what a sensible comment, finally someone has the balls to talk about it", no, you would just :O and think the guy is crazy ...

Anyway, I’d reframe the advice as “be (actual) friends with women and stay the fuck away from the manosphere.”
