Think again: they’ve been collecting our DNA from every source available. The place they really want to take over, we’re living in now.
They may want to rule over their s but they don’t want to kill us off. They need us to buy all of their crap. Plus, weapons targeting certain ethnicities would be difficult to deploy here, as there are so many different ones. Sub-Saharan Africa, on the other hand. They could wipe it clean and have the whole place to themselves.
Guaranteed, this is what they’re thinking about with ethnic bioweapons.
