That's because Plasmatic is obsessed, deranged, and one of the dimmest Hillbillies you will ever have the misfortune to see being a cunt. If an original thought ever crossed his mind it would be a very lonely journey.
And anyway you can't negrep me, but I'm happy to accept greyrep if it makes you happy.
I thought that Plas would realize that my reps being gray would have no effect on anyone's rep value. (Same as yours.) He probably did though. Perhaps his rep comment was simply "a funny."
Since my reps are all "valueless" being gray, I seldom give them unless a post really impresses me one way or the other. Sometimes the recipient of my gray rep gets confused because it's gray. Sometimes, he will interpret my gray rep as "negative" (like a red rep) despite his total not having been affected.
Then again, rep matters to only some. Others like myself tend to view it mainly as a trolling tool... nothing more. But for those posts that really impress me, I use the gray rep to drop a little personal note of appreciation for my gray repped peep.
