The reality is, we are all Americans. Some have drunk the koolaid, and some haven't. Some who have ingested the koolaid are friends and even family members. I prefer to engage with them as they're NOT enemies.
If I don't engage with them, they will view my inability to defend my position as a victory or worse: they will decide that my position is indefensible, and it will only serve to entrench their position.
Not everyone will I engage with. I try to pick my battles. For instance, I will almost NEVER engage at my place of business; there's simply no percentage in it.

Get rid of the need to be acceptable to evil.
When I was in sales, I called mostly on senior management of Fortune 500 companies and while I was very conservative, there was no reason worth while to get into political discussions with customers or prospects.
If I lost a single sale, it would cost my company 7 or 8 figures of revenue and me 6 figures and there was no way I would risk that kind of income for a political battle.
Being retired, I don't go looking for political fights, but I won't fade away. My risk is not financial but there are crazies out there.
It is prudent to know where you are.
