I'm no seasoned veteran player, more casual (In this case, only play occasionally, and often when multi tasking)

The community for the most part is already destroyed. A fair portion of raiders are elitist monkeys. That said, the biggest problem really isn't the parses, but more so the people using them, so most anger is completely misguided. You're going to have elitist brats on any game, regardless. In most cases I'd be for parsers, only to the extent that they can help players unfamiliar with their classes, for whatever reason. Assuming it's used in the right hands.

There's plenty of segregation already in the community. Can't see parsers making the situation much worse than it already is. Particularly with Square-Enix pretty much promoting them with their silly idea of having raids heavily based around high damage output requirements as opposed to proper mechanics(This is on the assumption that most elitist players already use parsers).
