"Troll" is not a label or a name, it's a verb. In this case it's a gerund version of the verb.
Your entire argument played on an equivocation on the the word "racism" and wasn't worth responding to directly.
Well my friend I beg to differ with you, the word "Troll" can be a noun when used in the proper context, as for not being worth commenting on well........, I wonder what that creature under the bridge was now.
I find all you PC folks to be the same hypocritical types that will kill doctors at an abortion clinic in the name of "right to life"
As far as equivocation of the word, it is YOU who played that card when you refuse to admit that racism can work both ways, but then I am not really surprised since being "right" is soooo much more improtant than being fair.
