That would be quite interesting in a country with 300 million people. Probably have to hire thousands of new judges just for social media, not to mention specialized law enforcement officers to hunt down these criminals. What about forums? Life, if someone said that here, would the FBI subpoena VGC records and IP providers?
I don't see how creating more jobs is a bad thing.
In Brazil, it's illegal to insult someone based on their skin colour, ethnicity, religion or nationality. There are almost 210 million people living in Brazil. In the EU, it's against the law to incite hate or violence against people based on their skin colour, ethnicity or nationality. There are more than 500 million people in the EU. Population should not be a problem in the implementation of a similar law in the USA.
