Jewish people often prefer their children to marry other Jewish people, as the Bible specifically prohibits them from marry gentiles. Should we say "f**k Judaism?"
In any case, Indy, it isn't good enough for you to say "f**k your religion," as freedom of religion is actually a constitutionally-guaranteed right, and it has historically been broadly interpreted. Now I happen to agree that this right doesn't extend to being able to deny people service while running a public business, but there is no need for you to make bigoted comments about beliefs common throughout the monotheistic world.
More interesting is your continued insistence that if a Christian doesn't follow all the rules, why should he tell others to follow any of them? For instance, if I decide that I've waited too long at a red light, and run it, how dare I tell you not to murder someone? Or if I say "homosexuality is a sin," but proceed to eat shellfish, somehow this makes me a "fake Christian," despite forgiveness for your sins through faith being THE BEDROCK PRINCIPLE OF CHRISTIANITY. Do you see how my actions don't impact the validity of the statement "homosexuality is a sin?" How a person can be a sinner but still make a completely valid remark about constitutes sin?
A little less slop in your thinking and you'd be way more effective. Stick to insulting people instead of making nonsensical theological points that are easily disputed.
