They are a form of human called an asshole. They spew what is scientifically called feces. Offer them toilet paper.

Nothing wrong with being a stripper. I make lotta money.

You should not listen to others. Its just a mindset. For some people, professions such as stripper, Pornstars, Sperm Donor, prostitution alcohol merchant etc etc are bad and not good for the society. Its their mindset and their mindset is not the reality of life.
Just always remember one profession doesn't define a human being. Their thinking does.
You do whatever you like to and want to. Just pay your taxes on time, don't do or involve any sort of criminal activity, don't do anything which could harm an innocent citizen or country.

I did get really drunk once and say something really similar to some girls at a party, I'm not sure why I did it, I think they may have said something to me first?

"Rude" is infinitely too mild a word for that. Whoever said that deserves to fall into a combine harvester and be chopped up.

Because people can be mean taking pleasure out of belittling someone else.

People have nothing else to do except act passive aggressive by throwing comments

Some people are prícks.
