Doesn’t this mean that the US is getting closer and closer to a dictatorship?

No it means US has a leader who is finally thinking rationally about China, instead of falling into the greed trap that most other politicians have been stuck in.

In my opinion, if China wants to be a part of the global economy, China must let the globe be part of its own economy. Facebook, Google, Twitter have been systematically forced out of China. Why should we let Chinese social media sites in our countries?

The specific act of banning TikTok seems petty and uncalled for, but we have to start somewhere.

No, we don’t. Trade restrictions on China are restrictions on the freedom of Americans.

I understand that this makes sense from a libertarian perspective, but I believe there are certain exceptions to be made when dealing with authoritarian, abusive, and dangerous regimes.

An example would be nuclear material and technology. US places a lot of restrictions on individuals' rights to trade these materials, but I believe it is necessary.

So not all restrictions on individual rights are incorrect, when it comes to trading with foreigners.

Blocking two companies is not restricting trade with China. It is restricting trade with two companies.

...

sigh

banning Chinese apps is xenophobic, yeah that's great logic.

yes, that’s the dictionary definition.

you’re also ignoring that you’ve proved the rest of the world that investing in US is not as safe as everybody thought so. it may byte you in the near future (i don’t wish that, though).

You are not even American. Please do not act like you understand the political process and it's everyday implications.

This is why you have no other retort other than "XENOPHOBIA!". Grow up.
