Prhaps an FAQ section would help.
My pet peeves:
(1) There is no caste system - what we have is Varna/Guna which is not by birth.
(2) There is nothing called HInduism - it is actually Sanatana Dharma.
(3) Hinduism is not a religion - its a way of life.
(4) "effulgence", "lotus feet", "puissance"
(5) Non-Hindus asking "why do Hindus put a mark on their forehead"?
