Bigotry is a great way to describe it, Snugs! I consider myself a conservative, but I feel I am also a realist. My personal feeling is that it is not realistic to expect that a true conservative presidential candidate will ever be elected. I hope I am wrong, but I think that a majority of voters are more moderate in their views. I just hope we don't end up with a President Hillary! because of it.
I use the mental image of steering a car or a boat when I come across these conservative 100%ers. Unless the helm or the wheel is kept near the center of its range, the course cannot be kept and no progress can be made.
We always have to remember that steering in the direction we want to go involves getting more people to go our way than our opponents get.
FR has always had the 100%ers - many were Keyes or Buchanan supporters. They will never get a majority to see the world their way.
