And having no minimum standards at all, no thank you.
I don't mind a robust exchange of views and even insults, but for me, the nazi stuff is unacceptable. I had an aunt, now deceased who was Jewish. 90% of her extended family in Europe were murdered by those nazi scum, her uncles, aunts, cousins.
It may be an apples and oranges comparison, but consider the example of extremely sexist and offensive insults being thrown at you Steephie, I'd regard that as being unacceptable as well.
If someone called either you or me a cork brained clown, then we cop it sweet and can respond with similar taunts / insults, but there has to be some standards that we collectively decide upon
