Oh man, the discussion contains so much nonsense, I don't even know where to start ranting about it.
Let's just take the scenario in question: a woman. A man. A child. The man doesn't believe he's the father - so there's a situation of distrust. The man gets a secret paternity test done - without the woman's knowledge and probably (since the child is surely still a baby) without the child's consent. In my eyes, a clear breach of trust. In the end, the relationship is already broken - by the mistrust.
So why are people railing against making secret paternity tests punishable? Because the alternative to a secret paternity test would be court proceedings and that would destroy the family. Seriously? Well, first of all, an alternative is also a voluntary and joint test. But if a joint test really can't be done, then the family is already broken - the court just makes the situation obvious, nothing more.
For me, the secret paternity test is just an expression of paranoia and inferiority complexes of men. And yet again, a practical general suspicion of these oh-so-evil women: they're all just sleeping around. Fits well with the Meisner remarks, because according to those, women are all just murderers.
If women are really that bad - why do so many men want to live with them?
Secret deception, snooping and suspicions have never saved a relationship. So there's no reason to particularly promote them - they are de facto an infringement on self-determination and therefore making them punishable would be completely correct.
But probably there would be a general strike of gene labs because a profitable source of income would disappear for them ...
