By what ethical code is this wrong?
Is it against the law? Is it against Christian principles? Is it against Islamic standards?
By what standard does this make you an ethically superior human being? Just because you hate church and I don't somehow makes you better.
Somebody has some serious ego problems here and it is you. You better start making some sense soon or I will be forced to stop taking you seriously.

Look, man, you can rationalize your lack of integrity all day... but you still lack integrity.
