Earlier quoted context omitted.
They would need to explain how TicTok brainwashes americans to vote(or not vote) but Facebook and Twitter categorically does not do the same thing. If "brainwashing" on social media exists then all should be made illegal not only the a small subset.
FB and Twitter no doubt brainwash people into all kinds of silliness - we've seen that quite vividly in the past 3 months. But there's not a whole lot you can do about them legally under US law. There is a whole lot you can do with TikTok and other foreign companies that represent a national security threat.
This could be fixed in many , many ways - like not allowing political ads, or not allowing targeted political ads, or labeling clearly what is paid political propaganda or the exteme solution , limited electoral budget (why should the guy with more money is more equal then the rest?? it is are torical question I know constitution in US allows this )
