This may have already been said above but I'm too intellectually lazy to read the entirety of the thread so I will just go ahead and weight in on this extremely important question.
1. If you are sufficiently appealing, either by virtue of your aesthetics or personality or some combination thereof to earn the trust and confidence of a foid to the extent that she will accompany you on a date then it seems to me that by a parity of reasoning, you would also have the basic prerequsite qualities to ascend, were you sufficiently desirous of doing so.
2. While inceldon is technically defined as not having any intercourse with women or perhaps, more generally, not having any sexual experience with women, we could agree that sexual experiences ought to be arrayed along a vast continuum with full vaginal penetration at one end and light touching on the other end. If a date experience is permissive of any such conduct, then it must be deemed to be an a priori violation of the rules since it could conceivably result in sexual gratification and the transcendence of incel status.
3. If we permit users who have successfully gone on dates to continue to partake of this community it will breed resentment, disgust and contempt amongst those of us who are less fortunate and this will prove to be a divisive force that will do a disservice to us all.
