That might actually mean something if the bans served a legitimate state interest, but they do not. That being the case, the bans are unconstitutional, as they expressly abridge the rights of US citizens, which is forbidden by the 14th Amendment. One might also keep in mind that the US Supreme Court has held that "One's right to life, liberty, and property, to free speech, a free press, freedom of worship and assembly, and other fundamental rights may not be submitted to vote; they depend on the outcome of no elections."

......Take a real long look at the U.S. map. 31 states and 10 more coming up soon. That includes California's Proposition 8. The vast majority of the American people and states know that going against Mother Nature has never been associated with American slavery, a totally different issue. Americans, religious and secular, are not fools.
Feel free to indicate a legitimate state interest served by these bans that would render them constitutional. I don't think you will be able to do so.
