No it means rotten for being outcasts like otakus.

Or rather, self shame, as if it's a bad thing. Well I guess it is in a way.. it doesn't really describe gay relationships properly and for some people is just considered "porn" which is commonly seen as "indecent". Except for liking porn there isn't a term used.? (Such as fujoshi and fudanshi)
Maybe you're right.
In context, the rotten part literally means 'disgusting for liking same gender couples'
