Surely you prioritise your reasons and try and find the biggest one, and if there isn't a massive one, just use a small one?
Like me, I hate Phil Collins because he made fucking terrible music. - BIG REASON
I hated Sesame Street as a kid, and I still do. Not because of the show itself, but Big Bird really scares me. - small reason. If I could find a bigger one, I'd use it. But I can't, so that'll do.
Surely you can find better and bigger reasons why you hate Phil Collins? There's so many to choose from.
