There are not two legitimate viewpoints. There is one, and many very smart people have spent a lot of time and resources figuring it out. Just like practically everything else in existence being something in the middle, it was decided that free speech is good with exceptions (your “b”, as it were). Language influences people, literally and figuratively. The mere act of knowing a different language changes how our brain works. So it’s not a stretch to understand and acknowledge that speech is powerful and can cause bad things to happen just as sure as if you did them yourself.
