For decades, and increasingly into the 1990s, liberals used the phrase "slippery slope fallacy."

They claimed that those square, uptight, Christian conservatives were putting forth a fallacy that once we give gays open permissiveness in society it would lead to further degeneracy.

That's what the PC police said when Roseanne became the first lesbian kiss on television.

That's what the PC police said when Ellen's character came out as gay on ABC during primetime.

That's what they said when gay culture came creeping in overtly in the 2000s and shit like Lady Gaga and Katy Perry cemented the new "all women are whores and bisexual and that's a GOOD thing!" status in the US (with some extra-heavy push around rumors that Lady Gaga was a man because hey, gotta start messaging early).

And finally, that's what the PC police said when gays were federally allowed to marry.

That was only 5 years ago.

Look how fucking steep that slippery slope was.
