Disagreeing with someone strongly is not trolling. A troll is someone who says something controversial just to rile people up. Please learn these terms before you use them.
Oops! I was wrong, class. The troll has yet to be annihilated.
Seriously: you called his Kaggath series a joke. What were you trying to accomplish if not annoy him? I guarentee you that calling anyone a joke is not gonna make them change their ways or turn them into a better judge. Insults through text do nothing but annoy people. You reticule isn't gonna make him decide that Sidious won, it isn't gonna make him see the error in his ways or anything like that. So, in the end, you're just 'riling' him up.
