Obviously it does, because the masses follow what the news says. You think people sat around during covid all by themselves, and decided to call people antivax? People who'd taken every vaccine, except that one mind you. You think people just collectively decided to start calling Trump a racist, instead of being influenced? Remember "stand with Ukraine "? Every liberal profile on social media was changed to that, changed to "i got my vaccine ", etc, etc. Absolutely the news has influenced people, and the other side as well, except they don't go out and attack people when triggered by a news story.
