Why ?
As repugnant as I find the alt/extreme right I disagree.
In the USA there is also a law suit going on where by a Baking firm refused to make a wedding cake for a Gay couple because it went against their religious beliefs.
They're a private business, surely they can do what they like too ?, surely they can choose who they will do business with ?, if you don't like it you can always go elsewhere.
See, if you advocate for discrimination against one group, you are advocating for discrimination against all groups, be they LGBT, Muslim, Baptist, Nazi, Communist, Republican, Democrat, Jewish, Women or any other group you care to define.
Who gets to decide whom you can discriminate against, the majority ?, if so are you now just advocating the white supremacist view point ?
This is a dangerous start down a path that will only bring grief.
And I am sure "Tim" would feel offended if he was discriminated against because he is gay.
