Sorry for your loss and the scene caused by your brother.
After the election of Trump, Prager did a show on this where mostly leftists were disowning family over Trump.
It really is amazing, and very disheartening.
During the eight years of GWB, my liberal family, associates, and customers never held back in their extreme disdain, and even hatred for the man, even if they knew my politics. Remember we called it 'BDS'?
Next up, eight years of Obama, and their behavior didn't change. Even though they had the president they wanted, they just could not stop poking us in the eye, while he went about"fundamentally transforming America."
During those years, it seemed to me that they were engaged in an orgy of violence against every conservative American value and tradition. Remember that Occupy and BLM were born during that time.
Now that Trump is in office, the wheels have completely come off the crazy wagon. Now, more than ever, political ideology means more than blood to the left. It's like 1861, all over again. My family split during that conflict, too.
