Makes you a troll.
Wrong.
'troll
One who posts a deliberately provocative message to a newsgroup or message board with the intention of causing maximum disruption and argument'

Having an off-shoot discussion within a thread is NOT 'trolling'.
Yeah...like you have NEVER, EVER typed a post that had little/nothing to do with the OP.

I STRONGLY suggest you learn what words mean BEFORE you use them.
That way - you will look more 'informed'.
Good day.
