Are you seriously telling me that you've never said you have disliked a person who you have never met. It could be anybody. A footballer, an actor, a politician, a TV presenter. You've never said to the lads in the pub, or turned around to the missus on the sofa and said I don't like him.
If you say you haven't then I'm calling you out now. I'll also say that, over the years, you've probably done it dozens or maybe even hundreds of times. Everyone does.
I don't respect you any less for having done it. Everyone does it. But what I do have zero respect for are hypocrites.
