A random Reddit post from a year ago isn’t going to change the origin of a word used for 30+ years.

That's the thing, racism becomes ingrained I'm not racist, so what I say, do and condone cannot be racist.

Often people can't change. It takes generations to leave behind. But even then, if not even acknowledged, it will continue.

I suggest being the change and tempering your language to match your intent.

So if you call someone dumb long enough it’s racist?

If you call someone fat it’s racist?

If you call someone clumsy it’s racist?

So basically everything is racist?
