Very frustrating dealing with these idiots. I, too, have family members like this and know that one day we’ll probably be fighting on opposite sides.
I just made my last reply to the a**hat. When people are wrong but debate honestly, there’s point in continuing. When they lie and use 100% dishonest tactics, it’s just like stepping in excrement, it does no good to anyone, doesn’t help clean it up, and you have to spend time getting it off your shoes.
