No.
Saying, "I hate green people!" is not incitement.
Saying, "kill all the green people!" is.
I don't think saying the latter should be illegal. 99% of the population won't act on that, and the 1% that does was already of a mind to do so.
If somebody says, "c'mon guys, let's go kill all the green people!", that might be different
Technically, this guy is inciting.
I don't think he'll change minds and gather support for his pro-war movement.
