Should the first amendment be interpreted in a way that makes it to where we cannot say that genocide would be good?

The way free speech in america works, is that you can say that it would be good for a person or a group of people to be murdered, so long as you don't advocate imminent lawless action to do it. You can say "I hope all homosexuals die and it'd be a good thing if they were" but cannot say "I encourage one of you to go to a homo's house now and kill them, tonight".

Should we make ourselves less free and have a standard of free speech more in line with what canada and europe has? Or should we continue to be free?
