Sin is sin, Yes, I never try to avoid this, in fact,
I say anything concerning this issue based on
'sex within marriage' that I believe it is God's will.

Anyone tried to DENY individuals bear sexual orientation somehow,
instead, to INSIST on unnatural sexual orientation can be obtained
exclusively by obsession or sinful learning, this person must have no
heart and brain. Why most christians SHAMELESSLY condemn that group of people?
because they have normal orientation and they don't care who are opposite,
this phenomenon itself is a strong evidence that kind of SIN is not easily obtained by learning.

Please think about it, how many people LEARNED to have SIX fingers????!!!
