That said, I agree the government probably shouldn't be involved here for the most part (slippery slope, government is a blunt tool, etc.). As long as your "speech" isn't actually harming someone (harassment, revenge porn, incitement, etc.)
As long as we're defending scoundrels it's worth remembering we already lack so many protections for non-scoundrels. In a lot of states you can be fired if your boss hears a whiff of collective bargaining. But I digress.
That there are limited worker protections in countries is a different problem, but is certainly not inhibited by too much speech, quite the contrary it would worsen the situation further. Civil liberties never suffered because too much speech was allowed, so the perspective to err on the side of freedom is only logical.
> there is simply no debate to be had about the basic humanity of certain classes of people
That is just an invalid generalization.
