In fact it should be the opposite: the right logic should be "
If there are still some women who like non-Chads (and even a 2/10 incel!), there is still a chance for me too!" It's sad how many incels haven't the right logic and make this kind of wrong logical constructions.
Some additional details:
1/ Acne usually isn't for life. The acnecels are a temporarily incels (if their inceldom is only due to the acne). So maybe that woman was clever enough to realize that the acne isn't a problem.
2/ The jaw matters but it's overrated by many incels. There are plenty of men with average jaws who still have relationships.
3/ The overweight is a problem but believe it or not, some women do prefer fatter males. Also maybe the man is losing weight currently and before he was more obese and now she likes him and respects him more for the efforts... or, the opposite -- maybe he was lean and after this become obese.
4/ In some cases (no matter how difficult is it to many incels to believe it) the character, the personality still matters even nowadays when people are more and more lookism affected. Maybe he impressed her with good gestures, care and so on. There are also these females who after get disappointed of prettyboys and Chads with bad personality are searching exactly for not attractive males but with good personality.
5/ In many cases it's about the money. Nowadays females and males are getting more and more materialistic, greedy... What if she is with him just because he probably has a ton of money?
6/ Maybe they're just friends or relatives.
7/ Maybe the guy wasn't 2/10 or at least for her taste maybe he was an average person like 4/10, 5/10, 6/10... What you see as ugly maybe pretty (attractive) to the girl. I'll give you example -- men may think that having hairy body isn't good but some women do like it. Or when you think that a long, big nose is ugly but many Asian females (and males) think that it's a very pretty thing!
8/ Sometimes just because a girl is with a guy doesn't mean she actually likes him... maybe she has some other reasons to be with him.
And, again, no matter what are the reasons, if they were a real couple, it's a lifefuel for all the incels because it showse there are still girls who're not going to choose only handsome men.
