Alaska passed an Anti-Discrimination Act back in the mid 1950s.  Alaska Natives weren't allowed in most white-owned businesses.  That bill sought to end discrimination for not only Alaska Natives, but for anyone living in Alaska.  If you open a business, you're inviting the public (everyone) to patronize your  business.  Therefore, you can't very well draw an invisible line and cherry pick customers.  It's over anti-LGBT supporters.  No religious beliefs or affiliation can stop the US Supreme Court's declaration supporting gay-marriage.  Accept that the LGBT community forever has parity with the heterosexual community.
