Racism Takes a Hard Left Turn

The KKK showed up at the South Carolina Statehouse to protest the removal of the Confederate flag yesterday (July 18th, 2015), and man did that mean Republicans are racist.  I guess we're ignoring the fact that a Republican governor is the reason it's being removed, and even stated:

"The strength and grace the people of South Carolina have shown over the last three weeks have inspired our family, our neighbors and the entire world. Our family hopes the people of South Carolina will join us in staying away from the disruptive, hateful spectacle members of the Ku Klux Klan hope to create over the weekend and instead focus on what brings us together. We want to make the Statehouse a lonely place for them. In doing so, we’ll honor those we have lost and continue to make our state stronger. "

Now, of course, in the article linked above (Think Progress), we had to see sh*t like this:

Yes...  of course they will, because - some bullsh*t methodology, I guess.  Or, because this guy said so.  Before I continue, let me point out:  I've been to some dark corners of the internet to figure out what these people really think (white nationalists, KKK, and just general assholes) - here's what I've found: they are pro-union (to protect white labor), they are pro-abortion (to control the non-white population), they are anti-capitalism --  this one for more than a few reasons.  Some believe capitalism is a Jewish construct, therefore cannot be trusted.  Others believe the benefits of capitalism are disproportionately distributed to the non-white population, and the rest are just idiots.

Wait - did I just list reasons to vote for Bernie Sanders?

Now, I didn't go into as much detail, which was obviously a pathetic attempt at ignoring the myth of the southern strategy:

Let's ignore the fact that the Southern Strategy didn't exist.  This person did not answer my question - which is common among those most affected by propaganda - and my question still stands:  why would an anti-capitalist vote for a Republican?

Let's consider: leftist economic policies are meant to "prop up" classes that they deem protected.  Well, white nationalists are seeking to do exactly that: protect their "class", or race.  In the same way La Raza votes for Democrats to protect the Latino population, White Nationalists will vote for the same style politicians to protect whites.

So my question still stands, and I will bring it one step further: why would anyone who is anti-capitalism, or favors protecting one race or group over another, ever vote for a Republican?
