can you point me to what I said that was bigoted?

Mr/Ms/Mrs all makes sense.

Mr -> You are a male

Ms -> You are a female

Mrs -> You are a married female

Mx -> You uhh feel like you are neither male or female or something. keyword being “feel”. The 3 above all are objective characteristics. The latter is not.

An adult should be able to teach kids without feeling the need to impose their own wacky views on them. Just use mr or ms. You are an adult, you can handle it.

Freedom of speech does not mean freedom from consequences

You don’t have free speech in a childrens class room.
