“I have liberal friends”
So that you are, in effect, dancing with the enemy.
I stay away from the bozos. When I find out that someone I know is a lib I sever the association, period, no ifs, ands, or buts.
I wouldn't. I'd use it as an opportunity to argue. You never know who you're going to convince. How do I know this? Because I was a Democrat many years ago who switched mostly due to talking to (very young) conservatives who easily combated my Dem/lib talking points. I considered myself a conservative Dem, but I realized after talking to these people that the Dems were wrong about practically everthing. Never underestimate the power of rational thinking. It can even convince obstinate Dems.
