Ugh. I hate reading this, partly because my very best friend (of 35 years, no less) and I are on polar opposite ends of the spectrum when it comes to politics. I hope we survive the current regime (and neither one of us is on FB either, so I can't even blame the internet if our friendship fails). There's a reason why I was taught not to talk freely of politics or religion in open forums when I was growing up.
One of my best friends has become extremely Conservative in recent years and I tend to skew to the left politically. We do not talk about it. I think we both know that it could potentially put a serious hurt on our relationship. But, sometimes the politics shows itself in other ways and it is getting harder and harder to keep my mouth shut. I am just keeping my fingers crossed that we (the US as a whole) can find our way back to center in 2020 and our friendship continues.
