That is a very narrow view. Take, for example, transgenders in women's sport. Do they have an unfair biological advantage over natural women? Are you a transphobe if you think so? Should you be cancelled and deplatformed if you think so? With so many potentially offensible groups, and with offense definition shifting so often, are you sure that something totally ok now won't deplatform you in 5 years?
I understand your point. I am not for or against here, I am providing context. Yes it is a slippery slope argument, however it is almost unique to the United States due to free speech being enshrined in the constitution. Elsewhere free speech come with the caveat "don't be a dick", so you can say what you want e.g trans women should not compete in women's sport, but abusing trans women athletes is not acceptable.and…
So if for instance in France I wanted to say "it's important to discuss the possibility the holocaust was an american manipulation", I m not a dick, maybe it s true it s important to discuss it, but you still have to shut the fuck up and think very deeply abt why you think that has to be said.
Most places free speech is defended, just challenged more. For instance the guy who dared say "for me, Islam is a stupid religion", got challenged in court for years but eventually prevailed: you can express your opinion of a religion. Just be sure that had to be said, cause it s gonna get expensive.
