The reason its alarming when people say repulsive things, is not because saying repulsive things is bad, it’s because BELIEVING repulsive things is bad. For as much as people rail against political correctness, that's really not the issue.
As Americans, we focus too much on being able to say whatever we want, when we should be thinking about what we believe.
It should bother us me more that we aren’t addressing the underlying cause of what people say.
Racism isn’t abhorrent because it is vocalized or written - it’s abhorrent because it's hateful, anti-human, & refuses to acknowledge equality, using an outmoded and disproven philosophy as its central tenet.
Lets question why people say what they say, not whether or not they have the right to say it.
