If you opposed gay marriage because it would adversely affect you in some way, you would not be a bigot. Gay marriage does not affect anyone who does not wish to be married that way. You are entitled to have an opinion, no matter how deluded, that it's morally wrong, etc., but you are not entitled to stand in someone's way of gay marriage in any regard at all and avoid the charge of bigotry. At present, the law in northern Ireland stands in the way, a defect that will be corrected soon, hopefully. In a small way that cake shop has tried to put an obstacle in the way of the future happiness of gay people, on no more grounds that they disagree with gay marriage. They clearly don't accept that there can alternative valid opinions to theirs that should be respected.   That's dyed-in-the-wool bigotry, in this case hiding behind a religion which they hope will attract more respect for them than they deserve.
