Or you could just read the statements of various politicians of our government:
Sen. Marsha Blackburn, R-Tenn: "It would not be surprising that the Chinese-owned TikTok is pushing pro-Hamas content"
Sen. Marco Rubio, R-Fla.: "We’ve seen TikTok used to downplay the Uyghur genocide, the status of Taiwan, and now Hamas terrorism"
And of course, Romney's explicit statement as well, when in context, it's actually far worse because it seems he is very concerned about lax fact checking on TikTok (which American social media platforms announced they are doing away with): https://xcancel.com/ggreenwald/status/1880979821901332773#m
I fundamentally disagree with all of these representatives. Americans are allowed to view all sides of every geopolitical issue and make up their own minds and vote according to their own beliefs. We should never ever be "shielded" from propaganda because we are smart enough to vote for and lead democracy, so we should be trusted as smart enough to ingest any geopolitical information existing in the world.
