I hope you realize there's nothing reasonable about this statement. IMO, most times when the right has been considered to be unreasonable, so to speak, it has been a response to the left taking things too far. And yes, this includes WWII; there is no Hitler without communism.
This is not to validate nor justify any extremists' actions but rather to illustrate that even when you are supposedly trying to appear centrist, you really aren't and what's worse is that you don't realize it. When this type of thing happens, you end up with bad outcomes. If you're going to be reasonable, also realize you're biased as I am (rightist).
