I think you and your friend Trevor Noah might be a part of the reason there's a lot of vitriol on the internet. You're basically claiming that half of the US voter electorate - who identify and register as Republicans - are racist.
Well let me tell you some things that others on the internet might not have the patience to tell you. The Republican party believes in individual liberties and was actually the original political party to end slavery in the US. Yes, you read that right. Abraham Lincoln was a Republican.
They don't want lower taxes and less social services because they hate minorities and poor people. They want lower taxes - and a smaller state - because they believe individuals have control over their destiny. That they deserve equal opportunities, and shouldn't be told what to do or how to think by the government. They don't think black people are worse and therefore need the government's help.
If you and other liberal elites think we need to hand hold a certain race of people with the implication that they're just not as good, then I'd say you're the racist.
If you want to discuss and debate actual policy, by all means. But if you're going to blanket label a group of people like that, then you're a part of the problem with political discourse in this country.
The Republican party also includes the like of Ron and Rand Paul, libertarians who a lot of the HN demographic identify with and support.
