And you don't know how ideas work do you?

There is PR and Marketing to promote any idea.

That doesn't mean a competitor did not invent something similar.

What matters is who obtains the capital to MARKET and PROMOTE the idea.

So when you say whites invented XYZ. That's because that is coming from European MARKETING and PROMOTION arms of European society.

Why the hell would they market and promote success from another area??

Who would care?

Would Europeans give a shit if some black African invented something cool in Africa???

NO!
