I'm appalled I didn't think that kind of bigotry existed anymore and least of all in a country like the USA which I have until now regarded as the most modern thinking country in the world. I can do very little to help from here but my thoughts will be with you and please think things through and try and get the better of them by legal means because they are proving themselves to be Neanderthal by their use of security guards to back up their demands. It can be done as I had a battle once with my local authority and stood to lose my house but I stood my ground and eventually won but it was a touch hairy at the time. Good luck, you'll be in my thoughts..........
