AIO for telling my little sister I wouldn’t be attending her birthday celebration bc Chris Brown beats women?

My (30F) little sister (27F) wants to see Chris Brown for her birthday. I don’t want to go because I refuse to give money to another evil rich person. She feels like I shouldn’t have brought it up. Should I have just went for the sake of my little sister?

Background: I’m the “kid that made it”. Went to college. Got a corporate career. “Made it out the hood”. my little sis on the other hand, (imo) made many bad decisions after high school. Dropped out of college, didn’t start a business etc. These poor choices cause her to be pretty unstable through most of her young adult life. She slept on my couch for a year, my dad’s place for 2-3, and other other sister’s for 2-3) she’s now finally on her own and thriving. I’m very very proud of her growth. However during her younger years, I did give a lot of advice about mainly her financial situation and her weight, some solicited, some unsolicited I’ll admit. But always with good intentions. Now I feel like no matter what I say, she thinks I’m judging or looking down on her. No were at this weird impass. AIO? Or is she seeing me through a lens of insecurity?
