Australia: Men who flew 'Its ok to be white' flag under investigation for racism

(Perth) So at a Cricket match down under on Thursday evening 3 men decided to unfurl and hoist a flag which read:

“It’s OK to be white”

Faster than a speeding bullet, the flag was taken down, the 3 men ejected , Cricket Australia said it took a “zero-tolerance approach” to racial vilification and the Polcie are looking into this as a racist hate crime.

Ok, I can live with that, now can somebody please explain why the following aren't treated as hate crimes:

Funny how all of the above are deemed acceptable , yet say its OK to be white and its a bloody hate crime.
