I am  hoping that this will also be used against these crazy religious nuts.   laws go both directions you know.  I would be able to refuse to sell to those wearing a pro-life button, because it is contrary to my religious beliefs.   I can refuse to sell to Catholic priests, because my personal beliefs are that they are all heretics and probably child abusers as well.   I can refuse to even allow someone belonging to Opus Dei into my store, because it is my sincere belief that they are a dangerous cult.  I can require all of my employees to have to buy insurance that pays for abortions and contraception, as my personal belief is that the world is over populated and I encourage everyone to use it.   And I will also require all of my employees to attend seminars on overpopulation and the use of birth control as well.  that is my belief so I can do it!
