I've never seen proof he didn't fuck a couch, any more than I've seen proof Glenn Beck didn't rape and murder a young girl in 1990 (look it up if you don't know what I'm referring to, is on the wiki).
Re slippery slope, conservatives love them: for trans rights it's "I identify as an attack helicopter", 20 years ago it was "what if people want to marry their pets". No real difference in the sociopathy of those offering up the suggestion, just a new front line.
I do agree there's a line: there's on one part the paradox of acceptance or whatever it's called which is explicit. In this case we are also saying it's weird to hold beliefs that are so out of touch with reality or the people they impact. It's weird to care what restroom people use, especially for those of us in states that have removed the victorian stigma on all-gender shitters. It's weird to care what sports other people play. It's weird to make up lies about Olympic athletes in order to push your agenda of making life worse for a 12 year old in Virginia. It's all weird.
Is this politics?
