The one thing I find scary about Hinduism
is their notion of a caste system. I've hesitated to criticize them for it because I don't know how widespread or central it is to their religion. But I find the whole idea to be an abomination.
I don't believe all people are the same. I know for a fact that some are better than others. But I don't believe they are born that way. No one should be condemned to a life of second or third class citizenship simply because he was born to the wrong parents.
I do believe some cultures are superior to others, but I don't think that can be passed through the DNA.
