Thanks for your comment, I had not heard of the minaret ban [0], which was an amendment passed by a double-majority (people and cantons), and was considered to violate existing constitutional protections.
I guess this is what happens in a democracy when enough people believe in doing something, even if that something is not right by everyone. Many forms of government are susceptible to this, depending on the culture. The world would be a better place if people had more respect for each other.
I'm also not sure how this is supposed to help minorities (motivated or otherwise), since the referendum is country-wide.
