Government isn't a big slippery slope, it's a balancing act between the people and the government. Law represents where we stand on that balancing act.
It doesn't matter really how the government tries to shift the status quo. If things get out of line with the will of the people, and they notice, change will be brought to a halt.
This is a common fallacy, especially with recent talk of the "Overton window" that's convinced people it's a good idea to be as extreme as possible instead of approaching the middle ground.
Your party and it's positions do not determine the average person's point of view. They determine what positions you can sustainably maintain, and wherever you move you will see raising or dropping support based on that.
The government won't just slide on over to some crazy extreme. This is why Russia, despite all their bluster, is still not managing to pull a draft. The people don't want it.
And this is why TikTok is so dangerous. By getting into the minds of the people, they threaten to undermine the foundation of our political process.
