I dislike Jones, and I like Anderson. I still spent a lot of time trashing Silva on Sherdog, so the GSP=GOAT gang could reign supreme; but it's all politics.
I suppose Jones & Anderson fans stick together for the same reason. They're the 2 steroids GOATs, so if one loses all legitimacy because of his PED usage, the other falls too.
Fedor and GSP are the clean GOATs so we run together; they also complement each other well. You can say that GSP is the UFC goat, and Fedor is the overall HW goat, and sleep with good conscience.
(Back in the days, BJ Penn fans use to flock to Anderson to have more numbers against GSP, so there is precedent)
