Threatening others is a crime. Generating false AI videos to harm another person’s reputation is a crime. Opinions are not crimes. It’s really not that complicated. People want to pretend it is complicated so they can control what can be said to gain power. Really not complicated.
It is pretty simple. If an action\opinion is deemed threatening then laws are created to stop that action\opinion. If there is no law making it illegal then it is just an opinion. So you can have a flag with a swastika, a confederate flag, BLM, OR LGBTQ.
