Not only are the countries he is saying have “fine” refugees don’t even speak English as an official language, Africa as a continent has the largest amount of countries that speak English:
Most other African countries speak French, Spanish or another European language as an official language. So what is the issue here? Many Africans have immigrated to Western countries and have integrated fine. It’s insane that Twitch is allowing this kind of rhetoric to be displayed in full velocity on this platform.
So here’s my take on this, because I’ve seen similar personalities make similar pivots.
This guy is a disgusting, bumbling idiot, but he speaks with certainty and condescension. The curious onlooker will see him, get trapped by the mindset you describe (“oh man, this guy’s a trainwreck, let’s see how much worse off he is than me”), find it funny and continue watching.
After establishing some sort of “trust” with the audience (“I’m a big dumb idiot who makes you laugh”) he pulls out the manipulative speech. “You’d have to be stupid to-”; “this guy’s a retard!”; “It doesn’t make any sense”, etc. Once you get to this part of the steam, you’ve already established that the dude’s an idiot, but you also think he’s funny. You’re faced with the decision to either laugh along with his “jokes”, or “accept” that this buffoon is “more educated” on a topic than you are. The fragile, uninformed audience these people are after are much more likely to go the latter route.
