Don't really see a problem with this, it's about as inane as "it's okay to be white" and should be fine as long as it's not wrongly aimed at someone or their property.
It's never been punishable to be white
Where did I say it had been? Far left and right are way too eager to find offense at the most trivial of shit.
Being white is a non-issue. There's zero point in bringing up "it's okay to be white" because it entails it's ever been bad to be white.
The line itself is commonly used to help slowly normalize and reinforce white supremacy, under the guise that white people are under attack. But I guess a line that's mirroring white nationalist recruitment propaganda would fall in to that area by design.
Meanwhile in the real world, some fanatics have become so indoctrinated in their ideological rhetoric, that they are literally arguing for police racial profilling of white people.
