that are being claimed by certain groups as offensive.
Apparently one person on the internet told you the word 'hysteria' is sexist. The term refers to a historical medical condition that was supposed to be caused by the womb, and women's propensity to suffer from this condition was used to justify their lack of ability to do things like vote. It therefore does have a sexist history. However, the use has moved on and most people don't know or care about the history of the word.
Did anybody actually tell you that nuclear power stations shouldn't use the term meltdown? Some people on a website told you they thought it was inappropriate to use the word meltdown in relation to NT children. Why is it 'political correctness' gone mad to use the word tantrum instead?
I can't see where anybody has accused you of committing a hate crime (any more than somebody was prosecuted for committing a hate crime in the OP's example).
There is nothing new about being polite and sensitive to the feelings of others. The concept goes back thousands of years.
