Banned for an unfair reason?

So, I think that I got banned for an unfair reason. This is the first ban that I've been ever had, and I admit that it was dumb of me to state it, but I thought that it was really weird. Taric got really mad about it, and I feel bad.

Here are the chat logs:

(obviously censored that n word) I don't usually use the n word, I guess that since we were winning I was just really hyped. I also have the clip right here. Do you think that I deserve the ban?
