Personally, I find it difficult to resolve why someone more aware of their sin should be any more accountable than the conditioned, predictable, gang-minded individuals that make up the great majority of the human race. Those lacking passion for truth or enlightenment have chosen their ignorance.
Or have they?
In most cases it's a simple case of arrested maturity - the causes of which are grand, dark, and ludacris.... Evil.
Passion for truth can be blinded by the dark light of confusion.
I think gays, and others, are quite capable of being great and good people on a social level - but in a selfish way. Much like myself really.
Doing good while doing evil - evil being that which is opposed to God's will. In the end it comes down to selfishness and doing what we want versus what we should do. In this vein I am no better than others - but again the difference is I see this and admit it and don't make odd reasonings as to why.
I don't want to bend the lord's will to my desires, though at times I admit I try. A christian that is gay should put the lord's will before their own, which is what I should do myself. We both have problems in that arena - but at least I admit it :)
