Yes, I see your points. I hope that this is a 'shot across the bows' that just concentrates people's minds in future campaigns, rather than wanting people actually locked up, and future campaigns having to get official clearance before running ads
But I have less faith than you that reasoned debate has much power to act as a corrective to the more extreme statements. Trumps strategy for example is clearly to repeat the lie often enough that it becomes the truth for those that follow him. Alongside the 'rigged election' claims, we appear to be in conspiracy theory territory, and that sort of belief isn't one you can debate people out of. Nor will people stop believing it once the election is over; if anything, a narrow trump loss will further reinforce his supporters views, and further fracture American society along race lines.
The progressive coarsening of political debate, with fewer and fewer things 'unsayable' worries me, as it will be hard to reign this back in, and I think real damage is being done to the cohesiveness of society by it. Perhaps the potential for criminal sanctions for going too far, even if these are never successfully used, will helpa llittle; but it's not going to address why this is happening in the first place so it's not really a solution, I'd accept that.
