Blatantly trying to interfere with elections -> if you mean by spreading opinions / propaganda, this seems generally under the realm of free speech. The government being able to silence opinions that disagree with it generally seems much more problematic than civilians being able to spread bad opinions

Cause riots -> Again, I think opinions should be legal. However, saying "hey y'all let's get guns and actively participate in violence" is not protected under free speech in any country I'm aware of, but is also not really my major concern with this legislation.
