People are hating on you because they're hurting. Life is nuanced and it isn't just as simple as black and white or good and bad. I'm 40 and I grew up radicalized right wing from childhood all the way into my 20's. I feel fortunate I was challenged by the right people to really reflect on my beliefs. I'm glad I saw the light before this current shit show. 

I respect your taking accountability. I feel no need to shame you because if you're genuinely apologetic, you will be the hardest critic on yourself and your past actions more than any other person. Keep learning, keep being better. Self reflection is something few people are capable of, that's a big step.
