Spencer is most certainly not (to quote you) "literally a white supremacist." Particularly in the actual literal definition of those two words!!!

The fact that fish offer up opinions such as "you want to argue semantics defending Spencer instead of issues is very telling"  may well be 'very telling' but not in the most flattering sense of the word. Factual definitions is not sematics.
 
In my opinion, fish need to stop swallowing the bait attached to a hook. 
Swallowing things 'hook, line and sinker' is not always advisable for ones well-being.
