"That's the definition of bigotry." Is it ???

The NI bakery were found guilty of discrimination and the court judgement gives a good idea of what discrimination means in thet contexts. akenaton's Salvation Army friends would probably also be being discriminatory (if they did a 'provide your message' service).

But is that, in itself, enough to be bigots ?

The only Salvation Army people I have known well enough to get into conversation with (as neighbours and as colleagues) were extraordinarily tolerant of other religions (or, in my case, lack of them). The neighbour (who had some sort of local leadership role in the Salvation Army) was, back in the 1970's, the only person for whom religion was an imnportant part of his life (and that includes national religious leaders in the media) who I ever heard ever heard express the views that a Christian leader in Northern Ireland was 'preaching hate'.

I don't 'get' what the Salvation Army are about, and it would not suite me, but calling someone a bigot for being uncomforatble about something which a democratic societies representatives have (rightly in my view) agreed is 'normal' seems a bit strong.
