For sure. I am white and I have no problem admitting white privilege exist, nor do others. Nor do we feel insecure to that it's not actually ok to be white. Of course it is. But we don't feel the need to constantly call this out or even make posters.
And people already bringing up BLM, no ****, no one ever thought of doing white lives matter, or rather all lives matter, but when black people speak up, suddenly every little racist crawls out of their hole and cries, oh wait a minute here, all lives matter.
