Do these guys do these crimes in their own country?
Yes, probably at a much higher rate. Especially in central and South America where law is corrupt or nonexistent, and gangs and the sex trade flourish. And let's not even talk about Africa....
Much of the world is a dark, dark place.
The average low IQ leftist in America (like some of my neighbors or relatives) may not fully understand this, but certainly the globalist and marxist demons who sit atop America's Democrat Party and woke political NGOs certainly DO know this, and they are promoting it for evil purposes.
Most likely.
