Israel’s setup is not perfect (and so is the one in Germany), but as long as you cannot show that there is any meaningful legal difference in the eye of the state between a couple that’s married (Christian, Muslim, Jewish, Druze) or in a Civil Union, I cannot see the difference to the system in Germany. I think (not an expert) the system in the UK in the same: you can get married either by the Church of England or by a civil institution - both are valid, both are equal before the law.

Edit: just check it, it’s true. “You can choose to have EITHER a religious ceremony OR a civil ceremony if you’re getting married.” [0]

So since we’ve established that it’s a common practice in some countries that marriages can be either religious or civil, but still equal before the law, could you please elaborate how exactly civil unions in Israel are discriminated against compared to religious marriages?
