We all have our different viewpoints, all of which should be expressed in the public arena without fear of ridicule, harassment, humiliation, etc. The same goes for mainstream view points and outlandish and controversial view points like the demographic dissension that Andrew is talking about. Everyone has their view points and everyone should be able to express them. This is America, we are a Democracy, not a Dictatorship.
Yes, Americans are legally permitted to make bigoted statements publicly, but there is no constitutional right to not be ridiculed for doing so.
