Nobody draws that conclusion from that premise because it would be retarded. It doesn't make any sense. So much for your attempt to paint a double standard.
Again, nobody says that. You are misunderstanding what people say, most likely because you hear what you want to hear in your quest to find examples of how you are equally oppressed.
I guess you're on an authority on what nobody has ever said and if I claim otherwise I must be lying.
I have seen MANY people say that female privilege is never a thing and some have claimed it's not even
possible. What people would normally consider to be a societal disadvantage to being a male is distorted to actually be misogyny. If this is applied generally then of course it has to apply to imprisonment rates. For example, women are kept out of prison because they're viewed as weak and less capable of handling it than men. Or they receive less harsh sentences because they're viewed as less in control of their behaviors, like animals. These are real arguments I've seen people make, to support a notion that every facet of society is structured against women.
As for the other side I gave, the justification for increased representation of black people among sexual offenders would be that institutional racism has forced them into a situation where they need to prove themselves with violence. Or maybe you could just assume that they're far more likely to be prosecuted for it because they're black.
Of course people are free to interpret things this way, as they are other ways. It just shows that it's not really that absolute or objective, or that a particular interpretation is not necessarily exhaustive.
And I've never said or implied anything about being equally oppressed with anyone. I don't feel oppressed at all, and I don't deny that some groups here generally have it a lot worse than others.
