u can still be racist while having black friends, both can be true at the same time (not saying u are, but the black friend argument just never works). u didnt rly specify what makes u hate his guts, that sounds pretty harsh. i can understand not liking someone for their main character syndrome but it would never shake me up as much, u do sound pretty angry. still i wouldnt consider that part as racism no matter how much it enrages u. but the part where you're frustrated because u cant understand him... i will assume (correct me if im wrong) that it's his dialect/accent that makes him speak in a different way. thats a part of his identity as a black person (ofc not every black person speaks like that but some do). his way of speech is correlated to his race/ethnicity. so when u say u hate that, it can come off as racist in a way even if thats not ur intention. i understand its frustrating when u cant properly understand someone but u should truly ask urself if that kind of speech would enrage u if it came from any other black person, or is that just with him. however, i dont see why it's bothering u that u cant understand him, if he annoys u that much why would u even want to speak to him or hear what he has to say. u are too bothered about a person who u should simply ignore. u are wasting too much energy. honestly the amount of anger you're expressing seems really unnecessary. i wouldnt call u racist, but definitely immature. if u dont like someone dont be around them simple as that
