In this particular case. both the protestor and Alt-right are on the same side it appears.   

Let me modify that a bit.  The racist are quick to show support for President Trump.   I would not say all Republicans are at all happy standing next to any of these white supremacist groups.    Clearly President Trump is trying to keep them as his voters, but President Trump does not speak for all conservative Republicans - as we can see from public comments in the last 24 hours.
