When you say it's unnatural, what you really mean to say is that it's unusual, which it absolutely is, occurring in a small portion of the population. There is little man can do that is unnatural, as we are not capable of breaking the laws of nature. You could make the argument that someone can act against their nature, like forcing a straight man to have sex with another man. This would be unnatural since a straight man is not inclined to do so. But a gay man would naturally have sex with another man, unusual though it may be. Insisting he have sex with a woman instead would be against his nature.
No one is asking you to join in. What the fuck is your problem exactly? Live and let live.

As is usually the case with hatred. Drop one and the other is guaranteed to fall, too. Pride parades are a direct response to unwarranted hatred, violence and oppression.
