So what if they are. Even if 100% of every Paul supporter voted, it won't be enough. Paulbots (and I use that term affectionately, not disparagingly) are a small group of a small group. They are vocal, active, and visible. But so are the gay activists and how many of them are there relative to the total population.
Paul needs to rework his rhetoric because he comes across as either isolationist, idealistic to a fault, naive, or just plain idiotic. Americans don't understand his message because it's so foreign to their indoctrinated ears.
So, in other words you agree with him, but he's too crazy for you to acknowledge that you want to support him.
