It will be a tough choice in November. Luckily, there are no laws about the type of hate speech here in the US. Let these people vent! At least we know who these people are. The same thing was considered at the start of the US involvement of WWII concerning the American Nazi Party. The people decided to not change the Free Speech law and the Nazi party dwindled anyway. We have enough people who would counter these hateful speeches such as the Sen. Orren Hatch mentioned above. Dr Carson is a neurosurgeon but has little clue on how the brain is programmed. We had some people called "config techs" that swapped boards in computers, but had no experience in programming them. Same difference. Rocket scientists know how to make rockets, but most of those don't know about the orbital dynamics to keep them up there.
