It depends, and sometimes the rejection is more unconscious (as in I just kinda forget and stop caring about their work and then when I'm reminded it exists I get more disgusted than happy thinking about it?). If it's just small stuff like the person has different ideologies or opinions but is not too pushy about it, then I don't mind. But if they're absolute dicks or if things that hurt me personally seep into their work then it becomes really hard to enjoy it.
Example of the prior: Some interactions I have had with a small group of other webcomic creators. I have had cases where I was eyeing someone's comic for a while and then they acted like an absolute bitch either to me or just in general. After that, I keep thinking "Ugh it's that uptight bitch" when I see their stuff, until I see improvements in their behavior. Which, I should mention, I always hope to see and I am always open to change my view of them. But them actually improving is extremely rare.
Another example would be Marilyn Manson. I was crazy about his stuff in my teens, so I rarely listen his stuff now because it's kinda "listened to death". However when I do I find it hard to decide whether I like it or not, since I did read his autobiography and know what a piece of biphobic shit he is. Buncha talk about "ALL WOMEN ARE INHERETLY LESBIAN" but all men aren't because man+man would be icky, except he has kissed men on cam (also didn't he engage in oral sex with one??? There is so much contradictory drama around this dude that I can't even remember it all), but he IS NOT BI!!!!!! NEVER!!!! HOW DARE U
Also it's because of my interest in Marilyn Manson that my previous sexual abuser found me, and many of the songs have dumb/offensive lyrics. Honestly I think only reason I still put a record on once in a while is because the sound is kinda cool and because it's nostalgic.
Example of the latter would be... Well almost any alternative band ever. Which is sad because I love the sound, but the lyrics are often preachingly pessimistic, pro-suicide, anti-religious, "life is worthless", or some other crap that will send me into a panic attack >_>
Wtf is the point in stinking down such good musical writing with such shitty lyrics? It might be because of the experiences I've had with certain extremists, but all I read out of this is "your loved ones rot in the earth and all you have is memories which you should be happy about i guess but your beliefs are dumb lol fuck u"
This is why music that is good on all points is a rare jewel that you HOLD ON TO FOREVER
There are exceptions to this rule tho.
YES HE IS BLOWING A KISS TO THE CAMERA WHILE SUGGESTING DOUBLE SUICIDE
YES IT LOOKS FUCKING SILLY
YES THE LYRICS ARE EMO AS FUCK AND I DON'T AGREE WITH IT ONE BIT
