No it's not.
That's an excuse that white people make that don't want to accept that their kids were racist little twerps before social media even existed.
And don't want to accept that white people are *less* racist since the introduction of YouTube and Twitter.
And don't want to accept that Black kids use YouTube and Twitter *much more* than white kids, but don't accept fashy nonsense.
And don't want to accept that newspapers and TV news push much more racism.
