I think TikTok is a garbage app that numbs the mind of the already willfully ignorant people, but I absolutely do not support the idea of banning it. The US is supposed to hold itself up as a beacon to other countries on the core ideas that people are free to express themselves and as function of that expression choose which peoples to listen to, even TikTok trash.

Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.

As much as I distain TikTok as an aggregator and disseminator of information it should easily fall under the classification of the press. It's clearly speech and an assembly of the people. Unfortunately the same twisted minds that established the FCC and said "on a radio (iphone of the day)" you do not have freedom of speech but only freedom to listen to government licensed actors will likely be able to use their evil ways to ban TikTok. Which effectively means that all content on the internet can be arbitrarily regulated FCC style. This is a massive step towards the US adopting Chinese style information suppression policies.

Every US citizen should be aware of the UN and adopting. While these do not carrying the force of law they were written in modern times and they absolutely express the sentiments of the founders of this nation around many issues. This is very clearly detailed in article 19.

Article 19 Everyone has the right to freedom of opinion and expression; this right includes freedom to hold opinions without interference and to seek, receive and impart information and ideas through any media and regardless of frontiers.
