In 2016 there exist something called DNA test.
The new law is about something different then you want to make it to be.
In certain countries it's illegal to ask for a paternity test if the mother opposes it. That's why smart or unsure father can always get one in a foreign country... It's like abortion tourism...
Yes, but you're citing Germany in your original post, where it is legal to have such a test. Crappy strawman argument, reported for fraud (just kidding).
Also, what is your point in making the post?
