English is the international language. It is mandatory to learn it as the second language in most parts of the world, even places you never heard of. It is especially a no-brainer for a person who grew up in Germany(which is one of the most developed countries in the world, and definitely has the means to educate its own people). Again, this is a problem of choice. And since Germany is a country that relies on importing educated people to keep its economy afloat, choices like these are self-sabotaging.

This isn't an english-speaking-forum, its an international one. That is the reason English is being spoken.

I get why the French is still angry about this issue and refuses to speak English, since it isn't French that is considered the international language, but English.

I wouldn't expect a French to understand this though.
