I never said it’s ok to be rude or discriminate anyone.

You can’t sue for harassment based on how one looked at you. Men can’t be sued for looking at someone. You perceived it as they looked at you certain way because you think they don’t like that you are heavy. But that’s your perception. Plus you yourself said that you “made a face” at a woman. You’d not like to be reported or sued for that. It’s not a grievable offense
