trust me, i understand this, and honestly i am a little confused about your stance on this issue.
looking at it from that view (all these decisions being so insignifigant), then gays should be awarded all the freedoms of everybody else because, well, what difference will it make in the grand scheme of things? it wont make any difference at all. people (in a huge scale of things) wont need to exist, and therefore being gay is a non issue
i get what your trying to say, but lets be real- we are on this planet, we are humans, and no matter how insignifigant any of our decisions may seem in the grand scale of things, they matter on a human to human scale. i still think, that on both scales, gays should have any right a straight person should and shouldnt be discriminated
