Sadly it's hard if that character is shoved in your face every time you turn around.
Non-Marvel example, I HATE Spike in Buffy the Vampire Slayer. They made him a regular in season 4, and I couldn't enjoy the show in seasons 5-7 when it became the Spike & Buffy program. I was a fan of the early seasons, and it's too bad there's a whole second half of the show I had to stop watching due to Spike and the clear bias writers had with him. Then even if you go to another show entire, aka Angel, they did the same thing. Shoehorned Spike into the last season there, and had him showing up Angel on his own show. Then there's the Spuffy comics. lol The latter half of the series if great if you like Spike & Spuffy. But if you hate both, you're out of luck. Because the show is no longer for you.
Then for me, Sabretooth is one of my favorites. But I HATE Wolverine & Mystique. Namely because they keep popping up everywhere & getting tons of biased fanboy writing. And Creed is the sacrificial lamb to both. It's hard to enjoy him in anything when he keeps getting thrown in with these 2, and made a fool of by both. I pushed through Weapon X because it was the only thing he was in. So I read & hoped to get some kind of decent story now & again. But Mary Sue Logan didn't lessen my Logan DNA hatred. Then when the writing finally got better, and Mary Sue left, Pak threw Mystique right in with very little time to breathe in-between.
Sadly, when your disliked character includes fan-favorites / pets that get tons of preferential treatment, you're out of luck with tons of stuff you wouldn't be able to read because they get put everywhere. But in order to see your favorites or other liked characters, the hated ones come tied to them & the hate continues to grow. lol
