I have no issues with parsers themselves. They're handy tools. It's the wanna-be raid hero cock weasels who use them to belittle others with the parsers. Especially when used to belittle roles that, mechanically, do not perform at the same level as other roles (say a Monk belittle a Dragoon for not having the same damage output, for example). And I've witnessed enough of these parser abuse over the 8+years that I have been playing MMOs, that I, frankly, would rather not have them. Especially when it's obvious that these self-styled raid heroes know nothing about other roles than their own.
