I Totally AGREE
I believe that you have to know the people you are talking to, even if for a little, you can open up some discussions far away from politics and religion to see how would they respond and see how willing and open-minded they are to different opinions.
Be polite to all, but intimate with few. ~ Thomas Jefferson
If you want others to be polite and respect you, you should be polite as well, and talking about religion and politics with people can open up many issues, issues of difference, that can bring up anger, or even sarcasm.
Politeness is a desire to be treated politely, and to be esteemed polite oneself. ~ Francois de La Reochefoucauld
And if you ever get put o\into a situation and can not avoid it; remember:
A polite enemy is just as difficult to discredit, as a rude friend to protect. ~ Bryant H. McGrill
😉 May you be in a company of politeness 😉
