It costs your time and energy. There must be a better use of your time than trying to shame nightclubs.

I'm responding to people who are using their time and energy saying they shouldn't be shamed. I wonder why they're wasting their energy with counter-shaming?

That user doesn't speak for me; my time is not so valuable today, which is why I thought to spend some of it casually chatting about a social media website I never had any intention of using. It was never my intention to shame you, nor to deny your right to shame others. If you feel as though I've tried to shame you, then I apologize for the miscommunication.

I don't shame people unless I think it will accomplish something productive. I wouldn't think of denying that you have the right to shame people for whatever reason you like, but I choose not to do it myself unless I see a good reason for it.

To affect their behaviour, obviously. To provide negative feedback.

That only works on people who aren't shameless and are willing to reevaluate their own behavior based on external criticism. Sometimes you have to pick your battles.

So back to my question: "What would shaming them for this accomplish? Is the idea to shame them so much that they pretend to like ugly people like me? What would be the point of that?"

What effect on their behavior do you hope to accomplish by shaming pretty people for not wanting to hang out with ugly people? I'm not seeing a productive reason to do this.
