He's asking for something they are hypocritical about, not your personal projection of the likelyhood of sexual success. That is ad hominem that only reflects on your personal perspective.
It's an answerable question, it is not a gotcha. An answer would reflect on ConPro though. One's personal disbelief regarding the one's ability to get a date does not really apply to the question.
Another layer: failing to accomplish a thing not equivalent to taking a stance against that which you failed to do. So even if the experience of ConPro users did reflect your projection, would not be a logical answer.
ad hominem
We get it, "if I'm involuntarily celibate there's no way these stupid chuds get women" lol... but is there something you think ConPro is hypocritical about?
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.
