I don't see how "useless lesbian" is ever funny.
When a group of oppressed people make in-group jokes about a common experience, it's often a funny way of bonding for them. If someone outside the group said it, it would be in a different context and not funny.
Common experience? Only in anime.
I'm sorry, I don't understand. Could you explain my existence to me a bit more? As a lesbian, I'm incapable of understanding lesbianism, so I'm really glad a man is here to tell me about it.
Being unaware of someone flirting with you is hardly a major issue. And lesbians are not oppressed, at least not in the Western world. Are they unfairly attacked? Yes, but they're hardly alone in that regard.
