Plz learn about secularism and communism, both are different.
I have done several courses in Sociology and I am perfectly aware of what Communism is. I was just saying that the kind of society that you were referring to (no religion in public
or private) is not Secularism. Of course, it is not Communism. Maybe I should mention Marxism-Leninism in its place? Anyway, in most of the significant Communist regimes, religions have been heavily persecuted, with the Soviet Union and China being the prime examples. This is what I meant.
and by your logic the Hindus in Germany should not tie the knot in a mandir and should not take those pheraz ??
Do you even understand personal laws and difference between law of that land ??
Yes, I understand the difference, I think. Anyway, about your first question - if there were to be such a law, then it would not be secular. However, what "the law of the land" argument does mean is that if the law requires you to register the marriage, then you have to do so. Perform the marriage as per your customs, but then follow the law and register your marriage.
And you would also be interested to know that Hindus in the UK (and many other places, I presume) are not allowed to have funeral pyres. They have to use crematoriums. And they abide by the law.
So, of course, your point cannot be entirely dismissed, because there is always going to be a constant balancing act between the law and the religion/culture of minorities. However, ordinarily, the minorities should obey the law and fight their case legally, or not go there.
