I haven't really followed this because it doesn't interesst me much but as I understand it once gay marriage is legal it will be by law discrimination and punishable by law those who do not want to marry gay people.
You obviously haven't really followed this, because your understanding is completely wrong. It even says so in one of the early posts in this very thread: Individual churches, and individual priests, will be allowed to opt out of performing marriages. Much the same as, well, everywhere else this sort of thing has become law.
Divorce and second (and third, etc.) marriages have been legal in most places for a few generations now but have you ever heard of a Catholic (etc.) priest being forced to perform someone's second marriage? Because I sure haven't. Nor have I, generally speaking, ever heard of a priest of any religion being forced to perform any marriage in particular (for instance, many churches will only perform marriages for people who are actually members of said church). I have heard of priests refusing to perform marriages for couples who they thought, for various reasons, were not suitable for each other; the usual consequence of this is that the couple has to go find someone else to perform the marriage.
