It's possible that it can show "prejudice and ignorance" but, in this case, it was more so there as a PuN and not meant to be taken so critical.
To explain the statement further,
It was suggested to "perm-a-ban" those that cause the problems being addressed by Dilla. So I said, using literary exaggeration, "if you perm-a-ban there goes the entire LrK clan". I was going for a sarcastic comedic value more so then a hurtful one because we all have played with you and hog at times where all this stuff goes down. I thought you guys understood my sense of humor alittle more. Stereotyping the clan based on your actions and influence is not necessarily showing ignorance because they are very dominant when your clan pubs in your presence. Just so you know. And if it makes you feel better, I will target some of those in all the other house clans as well.
*EDIT
wow, i'm turning into an asshole. I just read through this. I'm sorry for misleading you about my intentions, Curry.
