Because what the world truly needs is you telling women how they are and are not allowed to dress.
GP poster did not say anything about restricting how women are allowed to dress. He spoke about looking at women.
How about this: women (and men) get to wear whatever they like. And men (and women) are allowed to look at each other (in public, not talking about peeping toms here) as much as they like. It's your body, you get to put what you want on it. They're my eyeballs, I get to point them whatever direction I want. Autonomy and agency for all, hurrah.
If you think that the way a random woman is dressing in public means she wants to have sex with you, you're an idiot. If you think the way a random man is pointing his eyeballs in public means he wants to rape you, you're an idiot.
