This is a failure to understand centuries of history. It’s an understandable one, it’s one I used to relate more to and I probably still relate to it far more than I should.
The notion of racism requiring malice is so far from reality that similar defenses were dismissed almost a century ago in international tribunals which still shape the world.
It takes no malice to participate in racism. It only takes accepting it as given. This doesn’t have anything to do with anything that’s originated from the internet, from any perspective. It doesn’t make racism meaningless. Treating it that way does though.
“The” problem is that racism, as a societal background factor, is treated as the sea in which we swim, it’s “neutral” without an actor present to promote it. If it just “is”, no one is “at fault” and… the kicker, if your definition requires intent and there isn’t any intent for the specifics under question… it’s not just a mistake, it has defenses like these to shield and bolster it.
You can rail against “social justice” all you like, and I’m betting my response will show your railing resonates more here than it should. But your position is ahistorical and probably based in defensiveness about something you don’t need to defend.
