That is quite ironic. The misconception people have is that atheism is a dogma, a religion, a faith, a philosophy, etc. It is NONE of those. The one and only similarity (other than being humans and stuff) that atheists have is that they do not believe in god. I could care less about caste, and I wish I didn't know that my ancestors were apparently carpenters. Who cares?? Oh, apparently all of India (or at least enough of a majority to make this antiquated idea still an issue). People that I have met that care about caste have all been Indian, and none were atheist. Such hypocrisy, the religion preaches no caste but in practice they prefer the same caste (yes yes I know, not ALL indians are like this, but again it is enough to make it still an issue).

What is more ironic is that religion specifically preaches being humble - yet the most arrogant people I have ever met are religious. Another reason I don't like religion.
