My point is that an all-powerful being looking to punish gay men could easily just kill them in one swift stroke rather than expose non-gays to the behavior. Or do you think a wife who gets infected with AIDs as a result of her husband's indiscretions or a kid who gets AIDs from a blood transfusion are legitimate targets of "god's wrath."
That's what I meant by "doesn't discriminate."
The trick is not to take the statement literally. God does not act through lightning bolts striking offenders. He has set the world in motion; He has determined the way things work. He has given us His laws to guide us for our own prosperity; and He has left it up to us to choose to follow or not to follow these laws.
But the laws are not arbitrary; they are there for specific purposes. He loves us, and thus has told us how to act to achieve happiness and fulfillment. Thus He has told us not to do the things that will harm us. If we choose to ignore His admonitions, we accept the consequences of the world simply being the way it is. The world itself enforces God's laws, by simply being what it is.
