Believe it or not, I know what you are talking about.
During a time in my life, I thought, “What right do I have to not like something or someone”. Who am I to judge anything in this way.
I think we have a right to live out lives being what we are. So long as we do not effect someone else in the negative, its completely fine to like or not like things. We are individuals all with our own perspective and we have a right to that perspective.
A long time ago I had a group of friends (Yes I know I have become even more introverted than I was in the past). One day a guy that I ultimately didn’t like showed up and was accepted into this group. I was “repulsed” by this person. I tried to see around it using the thinking of “What right do I have not to like someone.” But it never took. Rather than enforce my will and try to eject this person, I decided to leave.
Its alright. You are you and you have every right to be you.
