If you visit some place outside your local city, you might experience a broader swath of people, culture, and beliefs. That makes you a dangerous person. You might start questioning why you've only been told one thing. Sadly, just traveling within the US can get you some exposure, but it's mainly just variations of the same thing with perhaps some external influences that have been absorbed. It's nothing like going to abroad and experiencing totally different cultures.

Scary social media videos about those foreign lands is just another tool to dissuade people from wanting to expand their experiences. If you research into some of this global industry, you'll see a lot of the influencers are spokes from central hubs of propaganda sources that shockingly are financed by the same people.
