This is probably going to rustle some feathers given that thread a mod stickied a while back, but it has to be said. EVERYTHING going on right now in regards to the trans crap and pedophilia is because of the forced acceptance of the gay agenda. You can say that they're piggybacking all you want, but the fact remains that the slippery slope "fallacy" has all but been proven true at this point.
Most people will generally agree that what two consenting adults do in private is between them and God. I won't say I don't care, because I don't want them to go to hell, but it's none of my business what they do in private, and I don't want to know what they do in private.
But this constant gay agenda acceptance push, legalizing gay marriage (personally I think marriage shouldn't be a government institution anyway, but that's another story), forcing everyone to compromise their beliefs and faith to make appease a fringe minority, etc. etc. has done nothing but cause a moral degradation of society.
Personally, I think it's a neurological defect. Which used to be the official psychologist narrative for decades until all of a sudden all mental health problems were "misdiagnosed because of intolerance" for hundreds of years. So I firmly believe there's probably a treatment for it just like how there's hundreds of cures for basically every disease, virus, and sickness known to man that's been held from us by the cabal.
But the point remains, and you can disagree if you want but everyone knows I'm right when I say this. If we don't rip out the entire rainbow tree out by the root, we'll just end up right back here in a few generations. It's just like any form of corruption, if you don't completely get rid of it, it'll fester and grow and come back once again.
And I don't know about everyone else, but anything that ultimately leads to satanic transhumanism and pedophilia is not something I find "acceptable" in any way, shape, form, or how.
"Tolerance" is what got us where we are now. Or are we just going to ignore that? Besides, the fact you started out with "We are NOT a Christian nation" shows your ignorance of American history, but for the sake of a neutral argument, I won't go into this from a religious perspective. Rather, I'll take a historical one.
Acceptance of morally degenerate behavior, specifically homosexuality and all of it's derivatives, is almost always a sign of a nation nearing it's lifespan. When things like homosexuality start being openly accepted, one of two things almost always happen to a nation. It either collapses soon after, or it experiences a revolution of some sort. The ancient Greeks and the Roman Empire are the obvious low hanging fruit given they both collapsed and are semi-well known for this, but I'll pick a different, more recent historical example.
The Weimar Republic and Nazi Germany. Post WW I, Germany was basically experiencing EXACTLY what we are now. Incompetent liberal government pushing every possible agenda while ignoring their own citizens, overprinting of the Mark to create hyper inflation, and finally creating policies that supported the moral degradation of society starting with, you guessed it, open acceptance of homosexuality and transgenderism. In fact, the first gender reassignment surgery was performed in the Weimar republic.
This is just one of many factors that led to the rise of Hitler. The people of Germany rejected the overt moral degeneracy being forced upon them. Of course I'm vastly oversimplifying but its not like I can write an entire novel in this one post. But my point stands. Even if you're not religious, there's a historical context for this, and those that don't learn from history are doomed to repeat it.
