racist is being bigoted specifically towards race.
there is a need for suchh discrimination, otherwise terms like "christian" are meaningless.
in other words: an X (christian, jew, muslim, etc.) is defined as one who subscribes to Y ideology (christianity, judaism, islam, etc.) and profoms Z acts relatet to Y (celebrating Christmas, Hannukah, ramadan, etc.)
so, if we don't make the distinction "all X does Z" what good is classifying in terms of X?
Have you ever felt so at one with the world, with the universe, with everything that is, that you were overcome with love?
That is reality. That is the truth. What we make of it is up to us.
