I refuse to discuss politics, here or anywhere. I have a neighbor who tried to tell me who I NEEDED to vote for!!! Like I can't decide who I want to vote for? People who try to bring up politics to me get told that politics is a topic not to be discussed. You have strong opinions about political issues? Great! I don't care what they are!! I don't want to hear about it.
I think I've told about a woman I met whose husband had recently died. Holidays came around and I asked if she was going to see her children. Her daughter was married and his parents always hosted. But she was not invited because her husband ALWAYS had to discuss politics, and he was on the opposite side of the son-in-laws family and by the time the day was over, everyone was so angry. So you are invited to someone else's house for a nice meal and you have to be a jerk because your political beliefs are that important to you? And politics is so important that you HAVE to discuss it, no matter the situation?? I wouldn't want you there either!
Another topic not to discuss? Religion!!!
