I think people forget that “Derech Eretz Kadmah La’Torah”. I hate when people do it.
And just for the record the issur of Chillul Hashem is greater by Jews so when I see a whole many bunch of one type of Jews doing stuff like this and I think badly of them and don’t wanna be like them – they are doing a greater Chillul Hashem then if a non-Jew is like oh, look at those Jews. So just be aware that even if its only Jews around, it’s still something bad.
(And I know there are rotten apples and all that. I’m just generalizing. Like when people say New Yorkers….obviously there are those who aren’t like that but…)
