Going to Tirupathi is a pilgrimage. Its misrepresenting religion. Faith by itself isn't irrational. You're putting 'Going to Tirupathi' and 'Not cutting your hair on Tuesdays' in the same bucket. This will only hinder progress in dispelling actual superstitions.

Categorizing all religion as superstition seems to be some sort of atheist superiority complex. (I'm an atheist too, btw.)
