Speaking of strategy, I've been observing a bit, while it may be entertaining I think we don't really make any traction.
My 2 cents worth, they're really not worth the effort.
I'd make the appropriate comment, provide sources/proofs and move onto the next troll. [I have, and do].
That way we'd [CET] get wider coverage and folk might go "what is this about..?" and check it out.
By Folk I mean the visitors not the actual OP's, they're too far gone IMHO. It's the curious undecided we want to influence. I bit like me perhaps.
It didn't take me long for the penny to drop :-)
Keep up the good work tho'.
