Lets see if I have this correct. Homosexuality is against your religion. You will sell a gay person flowers but will not judge him. If that same gay person wants flowers for his wedding you will not sell them to him. Gay marriage is also against your religion but in this case you decide to judge him. You don't see a problem with that logic?
Honestly I am completely lost with your logic and it is very disconcerting for religious freedom that people can't see such a basic distinction.
A) One is participating in a ceremony that celebrates a behavior that I believe is intrinsically wrong.
And the other is providing a service to a fellow human being that has nothing to with what happens to be his sexual preferences
B) I cannot judge anyone nor look at him any differently because I am a completely different person with different background feelings environment abilities etc... and I have no idea if I would be any different if was in the same situation he is in (and honestly I don't know of a harder "nisayon" than a young orthodox teenager who is homosexual ) However that does not mean I agree or condone the homosexual behavior
