Trolls come in all shapes, sizes and ages and when they become a stalking troll and want to pick a fight over everything you write - just write a final post that says "I have better things to do than waste my time arguing with a baby. Have a nice life." Of course the troll will goad you - they are predictable and they want a rise out of you - don't succumb to it. Don't fall into the trap of trying to have the last word with continuous posts because that won't work. The troll will never stop because they are attention whores and you are giving it to them. If you want to feel like you've won, just stay silent after that last post and watch the little idiot post over and over again with insults that nobody cares about. Trust me - it's the best way and you might even get a laugh out of watching the little twerp driving himself slowly mad because you're not answering. Heh heh.
