I wish these republicans would stand up against fucked up individuals like him. I would like to see the moderate republicans get up and stand up against the radicals and disassociate themselves from the crazy rather than facilitate it. But to be honest, it's the radicals who make the loudest bang and may not represent all. Regardless, nobody with those attitudes should have political power - yes it's allowed because it's democratic, but I don't think people should vote them in and with current power? They should make votes of no-confidence, use the system to keep the crazies out of power. Bring out the more reasonable republicans, bring them to the floor. Unfortunately, humans are gullible creatures and can be sold a whole line of bullshit to convince them. But there's 3 types of people in this world you can't trust, politicians, journalists and preachers, sure there's honest people in all 3, but in reality they have their own agendas and will tell you whatever you want to hear so you buy into their bullshit.
The saddening thing is, this guy isn't the only person in the world with those kinds of opinions and there are those who have acted on such things. I wouldn't worried being ashamed about your country or race because there are many who'd stand beside you with the same bad taste in their mouth after reading that.
However, everytime I read something like this, I lose a bit of faith in humanity as it seems we managed to push and push harder and harder to progress ourselves as a species in a positive way, but there's this resistence holding us back and at times I do wish I was another species and on a different planet separate from all the fucked up things about humanity, but you can't escape it. For me, the issue was not so much the racism, but how the intellectual dishonest and lack of compassion in the lives of fellow human beings. I'm not so much worried about the "black people should be grateful", it's horribly offensive, but what frightens me is his bit about the immigrants. Combined with the racism, I'd feel very worried if he were ever to act on his convictions or if his party were ever to take him seriously enough to do it, then they wouldn't be the first and probably won't be last.
So you kinda wish humanity would just fucking evolve.
