There needs to be a word for when you have a negative association with someone solely because they remind you of someone else that you don’t like. Its like completely not fair because its not because of anything person 1 did, they just have some attribute that reminds you of person 2, and person 2 was a complete barrel of ass varnish.
Like Louis CK is one of my favorite comedians, but there is always this background of aggravation in my mind when I watch him because how he talks reminds me of someone that I don’t like. Or people named Travis. Every Travis that I’ve met has been an asshole, so I may be unfairly judging any new Traves that I meet.
