Is "purist" disparaging?

I envision a purist as an angelic creature, dressed in flowing robes and glowing with a soft golden radiance, and speaking with an almost musical cadence of vocal tones which please the ear. The 5E Purist waves a hand over the freshly minted D&D tomes, and with poise and charm intones the rules which are scribed therein for the good of the flock, so that our adventurers may roll the dice of fate and test their mettle. Ahhh, the purist speaks soothe ... except regarding 5E Bards which are totally broken.
