Where does your conclusion stem from? I haven't been aware of the German government discriminating against these groups, nor of the CDU proposing laws to do so.

One issue I can think of is same-sex marriage, but there's laws enabling same-sex couples to get into a "Lebenspartnerschaft", which is functionally equivalent to a marriage. There is some areas where things differ, like certain clauses in the explosive ordinance regulations, criminal rehabilitation law and census regulations. Granted, it doesn't say marriage, but it's close.

Regarding the legal treatment of Muslims in Germany, there seems to be two issues. One being head-scarves, the other circumcision. On the former, the German constitutional court ruled in January 2015 that a general ban in schools is unconstitutional. The latter, the state court in Cologne ruled as grievous harm, but this was later overturned by a law passed by the Bundestag.

Really, the spirit of the formulation the CDU used does not specify which God. Even taking it in bad faith, one has to remember that Islam and Christianity are both abrahamic religions, so they share the same god, which makes it doubly moot.

There are legitimate issues to be talked about in this context, from integration of immigrants to a growing anti-islamic sentiment in Germany and the rest of Europe.

Christians outside of the US are rarely that conservative or judgemental of others' choices. On the contrary, being able to accept those differences is one of the core beliefs.

After we got engaged, my wife was told by Swiss missionaries living in France that it would be wrong marry me because I'm Roman Catholic. Furthermore they assumed that she would have to become a practicing Catholic as, after all, the husband is the head of the household and it would be immoral for the wife to persist in different beliefs and practices.

Granted, the percentage of people in the US that would agree with all of the above is much higher than in Europe, but it's not like conservative Protestantism (or Roman Catholicism for that matter) doesn't exist there.

Not that I feel a distinct need to defend stereotyping statements towards large disparate groups of people, but I think the original statement was meant to imply the general Christian populations of other countries. People that visit other countries specifically to spread their religion may have somewhat more extreme views than people of the same the general population of their originating countries.

Do you have actual experience with Christians all over the world? I've certainly met a few that put the lie to your assertion, from a variety of places, and I suspect you're making the classic mistake of calling the place you live "the rest of the world" in comparison to the US.
