Why the Arizona Gay Law Makes Me Think Overpopulation

The Arizona "gay law" clearly goes beyond gay people as it basically is asking the question, "as a business owner, do I have the right to discriminate my business to anyone based on my personal principles?"

The answer may very well be "yes" which is neither all good nor all bad - but plenty bad. I understand that people do not want to be told how to conduct their businesses that they built with their blood, sweat, and tears - and I get that - but I also do not understand why so many people are obsessing about who they get to oppress.

Why are we so afraid to love our neighbor? Is his skin color really so different that it causes hatred? Is his god so vastly different that his mere existence is a threat to us?

It is certain, according to the infallible law of sustainability, that earth's population can only grow so large before a) there are not enough resources to sustain the populace and b) the "organism" of the populace as a whole is too large to sustain itself and function correctly.

Admittedly, part a is the more commonly accepted theory whereas part b is more of my footnote of an observation.

However, with this theory in mind, I cannot help but wonder if this "gay law" in Arizona, possibly to be followed by Georgia and other states, is not a sign that our populace is indeed too large and that nature is starting to throw some curve balls. Basically, is it possible that there are so many people that our collective energy is trying to eradicate parts of itself so that that rest of the organism can continue to thrive?

I have a similar question / hypothesis regarding homosexuality as a natural, biological response to overpopulation.

What other reason do we have to keep hating and fighting our neighbors after all of this time, even when the deity that we fight for clearly commands us to love our neighbors?
