1. Your first part is theoretically true, but the charge "racism" has been thrown out so much it means nothing anything anymore.
2. If you're going to demand people justify posts (by some arbitrary means of "adding value"), most of the UofL fanbase has violated your demand over the past week. I haven't seen you chasing them, demanding they justify the value of their contribution to the "conversation." (That's a kind response to the 2nd part of your post. I can remove the kindness and respond more directly, if necessary.)
