When I attended the University of Phoenix in 2005, we were taught that to support same sex marriages because it would become legal in most states and we'd get in trouble if we didn't. That GLBT people might be key employees and that diversity is a good thing. So if you have religious beliefs against gay marriage, support gay marriage anyway.
Eich has religious beliefs against gay marriage and donated to a charity that tried to strike down a gay marriage law in California. Those donations were made public.
We're going to see more of this as people hold religious beliefs that don't believe in gay marriage. Many religions are going to have to change.
