This is all very interesting. Our family has always talked politics along with other topics. People are well read and I think everyone has an open mind about tolerating the others point of view. I know I do. But then my cousin (you know the one. The one who posts the crazy conspiracy theories on Facebook) she lives too far away to come. We have relatives who are elected officials and ones who have worked for Congresspeople. They usually have a very interesting view point and I like to hear what they say. Of course the ones who have worked in government seem to be more grounded than the aforementioned crazy cousin.
I have a friend who has a very different viewpoint than I and posts all these extreme political posts on Facebook, mostly to argue with her siblings. A friend and I pointed out that everyone can see what you post and the fights you get into on Facebook. She recently has been posting positive thoughts and pretty pictures of nature. 
So my view. Political discussion that is civil, great. People who believe Russian bot posts, crazy! Fortunately the people in my family don’t espouse the Russian bot theories.
