Given that Indian /eastern society tends to push the faith of the father onto the kids as the only choice , which my folks were also worried about because of relatives speaking that way I can see how an unconverted male would be an unknown quantity and there would be a huge risk of apostacy from sikhi if the female is not versed or willing to bring up her kids in sikhi . In my case, we had to talk through such future things as a couple and in the gurdwara when we got married we made an explicit promise to bring up kids in Sikhi . Maybe it was just us because any other marriage I had seen there no granthi etc ever gave that sikhiya.
In the case of the mona punjabi , the couple should have been offered the marriage course like catholics do before the anand karaj so that they know just what they are entering, promising etc and then decide if they will try for anand Karaj by devoting themselves to Guru ji .
Being a sikh is a privilege not a right ...so let's give it the respect it deserves
As I heard in a video yesterday "these days sikhs say why do we need to have amrit , guys. Guru Gobind Singh ji begged for amrit to be worthy of being called Singh , are you more special than Guru Gobind Singh ji?"
Another pangti came up in my feed where Guru ji says you have no strength/will to keep your kesh and try to say that times have changed , this comment was made to sikh back in the time when Guru ji was in Deh form so you can see resistance has always been there and Guru ji has given his faisla at that time
