There absolutely are genocides of “ugly” men.
Disabled people, black people, homeless people, and gender non-conforming people are all groups that are frequently seen as “ugly” and have been genocided at some point.
This is what incels do. They take perfectly legitimate problems and twist those problems into excuses to hate women.
Yes, those systemically deemed as “ugly” are oppressed. But the solution isn’t anti-feminism or stopping people from having individual preferences. Oppression of those deemed as “ugly” existed long before feminism, and there’s nothing wrong with individually finding someone unattractive as long as you don’t recruit others to also find them unattractive.
