Are good manners universal that trascend politics, religion, and climate change?

Please, thank you, and you're welcome transcend good manners. They are required!

Yes, good manners have nothing to do with those things

The lack of good manners and common courtesy many people display has little to do with, I think, any of those things you mentioned.

Definitely.. They are the oil that lubricates society and allows it to function

Transcend ? No.

But good manners are welcome in these disciplines.

i would say yes
