Why are male idols thirst threads made by female fans ok but but if a male fan make thirst posts on female idols then he is creepy

Why double standards?

Double standards don't have reasons.

Because most users are females and they feel uncomfortable seeing other women being objectified. But when it happens to male Idols they are on the receiving end don’t feel uncomfortable so they don’t care.

It probably depends on how this fan is talking about that idol.
