You shouldn't call equality movements cults. Nazi Germany was a cult, Scientology is a cult, wanting equality is not a cult. And I'm only asking you to be more respectful to our happiness and celebration, not necessarily what we stand for.
And why do you think it is abnormal? Homosexuality has been found in over 1,500 different species of animals; clearly it's something natural considering how much you can find it in nature.
And if you consider that marriage, then go ahead; marriages have had quite a lot of different meanings among people throughout human history. The thing is, this is The United States of America, the world's melting pot, the land of the free, etc.; having everyone's idea of marriage (under the terms that it doesn't hurt anyone)be legally recognized so that they can receive the benefits legally wedded couples receive should be a no-brainer for a country that attempts to stand by mottoes like ours.
If you have problems with homosexuality, I'll be honest and say that that annoys me and flusters me a little bit, but you are entitled to your views and opinions. It seems to me like your issue is that you don't really like LGBT people and all this new legislation making them equal citizens to you feels like complete LGBT acceptance is being shoved down your throat. Although maybe that may be how it is in the media, as far as the laws themselves go, it's not. Gay couples being married doesn't affect you. Their relationship hasn't changed much than it was before they were married; the only thing changed is their benefits, which are their concern only. I know LGBT stuff is all over the media, and to you that must be pretty annoying, but as far as what the media is hyping about goes, it's not a big problem to you.
Basically/TL;DR: we're not a cult, homosexuality isn't scientifically abnormal, let's agree to disagree on what is and isn't marriage and respect each other's opinions on something with such a wibbly-wobbly definition, and although I can imagine the hype must be annoying to you the laws themselves don't directly affect you and you needn't worry. And as always, have a nice day.
P.S. I should work on not having run-on sentences...
