Are people here too rude?

[Jackalope]

No one said you have to change.  You either interact here with the different personalities or you don't.  That's your call.

Start a big long ignore list if that makes you feel better.

If an echo chamber is what you are looking for, this probably isn't it.

Again, it's odd to me that you equate a desire for mutual civility and politeness as an echo chamber

Hard pass.
