Half the stuff Trump says is some insult to someone. "Owning the libs" and "libtards" has been a thing for a long time. Remember when the tea party said Obama was literally Hitler for trying to come up with a better health care system? etc. etc. etc.

But somehow everyone else needs to be on their best behaviour and as soon as they say "fuck you back" in response to a torrent of "fuck you"s it 's a big deal.

If you want to talk tone and insults then you're definitely starting at the wrong end.
