I support their right to do whatever they want with their own business.
As I support the A&W in Frisco having their religious messages on their menu board (Hell, I even give them business just because of that, you know corporate has been trying to push them to not display Christian messages for years now).
I only wish that more people supported the 1st amendement even when it goes against their own beliefs.
The amount of hateful posts I received in my recent shenanigans, mostly from so called defenders of the Constitution, was just unreal.
If this business is against gay rights, well it's their right!
You cannot push your rights on somebody infringing on theirs.
