Or.........The obsession is all in your head. You can read a few threads about Blacks in here from time to time, but that's it. A few. You can also read a few threads in here about lawyers from time to time. That doesn't mean terbites are obsessed with lawyers. If you take the threads about Blacks more personally or more seriously than you do other threads, then you've built them into your own obsession. But saying it doesn't make it so.
I was being at bit sarcastic due to another post and I wasn't being that serious.
But I like your idea better.
