To me, the plethora of internet memes has made them, for the most part, redundant. I find these apostate memes pedantic and humourless. Everyone is an individual, and folk will always have different sensibilities. *shrugs*
They do tend to make 'apostates' appear to be mean and bitter, though. And some 'apostates' are mean and bitter. Just like any other group, there are all shades of ex-JW.
