“some of them probably should as well, but its more on you when you are arguing from not even a flimsy position, a none existant one!”
This is getting tedious. But. Why only some of them? Which particular insults do you think are acceptable and which aren’t?
And I have said hat a) I didn’t recognize the slogan as a quotation. And b) it doesn’t actually matter whether this particular T shirt is real or not - the principle remains, and needs to be discussed. Girls’ clothes very often have this sort of stereotyping slogan on them.
You may not think it’s important, but I see no reason why you (collective you) should be so obnoxious to people who do.
