That's a ridiculous and needless comment. I didn't support the bill for several reasons. However, it was not an "anti-gay" bill, nor does this veto suddenly prevent discrimination. It is already legal under AZ law to discriminate against gays. That is simply a fact. The intent of this bill was to give businesses added protection from being compelled to violate their religious beliefs (as has happened in CA and NM). Having said that, it was redundant and created extremely bad PR. My understanding is that it was worded in a broad way that could lead to more discrimination. Those are all reasons that Brewer did the right thing be rejecting it.
Of course, this doesn't solve the issue of businesses in other states being compelled to, say, bake a cake for a gay wedding. As a Christian, I don't consider homosexuality a sin. But millions of others do. Being compelled under threat of force, loss of income (etc) to essentially endorse something that violates a person's religious beliefs is an appalling thing. We're not talking about refusing to serve a customer at a restaurant or retail store because he appears to be gay. We're talking about compelling participation. One has to wonder...if we can do that...why can we not force churches (who get non-profit tax benefits) to perform same sex weddings?
