That is certainly part of it. I can't in good conscious sit here and demand I be left alone to live my life (ironically not taking part in the vast majority of the things here listed) and not offer the same "as long as your actions don't directly hurt me, I don't care what you do" line of reasoning to others.
I do understand that this approach has flaws and consequences, but it's generally where I'm at. I don't have the energy to police other people's lives to the degree others want to, from both sides of the spectrum.
I'm quite bothered by it as well. Since I was a child I've never understood why people care what sex someone else is attracted to, unless they themselves are attracted to an individual that isn't into them as well. Therefore I've always been a very big supporter of the "lgbt movement" by default. Here was a group of people who just wanted to be able to be honest about how they feel and live without their lives destroyed in the process. Nobel enough goal, IMO. What consenting adults do sexually in their privacy is not of my concern.
But now, I'm no longer able to support the "movement" on whole. Because these very same people that assured they only want acceptance, are now actively trying to destroy the lives of "others" now that they have popular support. They have pushed their "good thing" into a negative, and become what they have spent decades trying to defeat.
It's rather sad.
It's collectivism, plain and simple. We've been infected, and can't cut out the tumor any longer. Our society, our government and our freedom is now a terminal cancer patient. I understand my general apathy described in the first paragraph doesn't help, but at this point, I'm not so sure a soap box or ballot box is going to turn this tide.
I'm convinced the money will run out before the leftist purge independent thought from our nation, before their "PC Newspeak" creates thought crime actually punishable by government and before the reeducation camps come into full swing. However, if I'm wrong, I can't wait to have long and wonderful conversations with a lot of you at said camps.
