I'm only letting you in on an objective fact when I repeat that you are projecting an ad hominem conclusion onto them based on your personal expectations. Your expectations are rooted in your personal experience (which you have knowledge of) and not their personal experience (which you do not have knowledge of).

Does it sound like I could be wrong? If that's the case, instead of simply saying so, you would have the ability to prove it with a link to even one ConPro post in the forum's entire history, a post advocating marriage for everyone, from a user who excludes themselves.

There is an ongoing debate between incels and the normal men there, but the incels argue against marriage.
