They think it's part of one's belief system.
If you are on the left, you are good. If you are on the right, you are bad. Your actual behavior does not determine good or bad.
Anything that BLM does is justified because they are oppressed, even burn, loot, and murder.
Voting for Trump, even if you are a nice person in deeds that never hurt anyone and gives time and money to charity, makes you a horrible racist that wants to keep oppressing black people.
The same way objective facts are now racist because obviously science and math are rooted in white supremacist ideals.
Remember, if you are a Trump supporter that does nice things for your neighbor, you are trying to buy/guilt them into loyalty; just like Nazi Germany!
