I can understand why people would be against a radar, but I never understood the obsession with hating on parsers. The only thing it does is read numbers off of your combat log in real time and displays them in a way that's easy to understand. You could do the same thing with a pen and paper if you sat there and scrolled through your combat log for an hour, the program just expedites the process. Otherwise, parsers don't typically display any information that wasn't already available.

Every time someone is adamant in their stance against parsers I always imagine someone who's bitter about being kicked from a party because someone else parsed them and said they were underperforming. Parsers are useful. A few jerkasses using it in ways you might not like doesn't make the program itself bad and is no good reason to take it from everyone else.

I don't personally use them (because I'm lazy), but more power to someone who wants to make regular use of them.
