There is no better concept than that of 'anti-racism' to sum up the sentiment in this article.

When you have to prove you are not something, there is the assumption of guilt. Before there was an implicit acknowledgment that we live in a world where there were laws against discrimination and this protected people.

Now we live in a world where we have to prove our thoughts are not racist and the assumption is we are guilty unless we prove otherwise.

That is how you create a Stasi-style climate of fear. Where anyone, anywhere can be accused of wrongthink. And this is how we learn that the safest position is to agree with the crowd lest you be the next one lynched.
