For a Sikh to eat "any" meat that happens not to be Halal is to make himself into a lobhi dog.
You're using this to justify eating non-Jhatka meat? The 2 minute video you posted was a beautiful summary of Sikh Rehit by the Hazuri Babaji. It was not a long exposition, however. Are you seriously claiming that Hazuri Sikhs eat whatever meat they can find, just happening to weakly ask if it's Halal?
Most Nihungs support Jhatka? I would genuinely like to know one that does not.
The link you posted does not support your assertion. It talks about the theory behind Jhatka and how that's the Nihung way. How does that support your assertion that there is no specific Nihung maryada regarding meat?
That's actually not true, bro. More children usually means more religious children.
For one thing, in large families, each individual child has less pull on the head of the family. The head is more respected, and therefore the children obey more. They learn that they are not the be all and end all. That there is someone above them.
Why would you want to teach them individually? It is considered more effective to teach people as a group. Guru Sahibs call this concept Sangat. Humans are social animals, and the more people that follow a certain thing, the more firm they are likely to be in that belief.
Furthermore, in a typical two-child family, there's one girl, one boy. Each has new clothes and other stuff for every year of their life. They get an entitled mentality. A single child is the apex of entitlement mentality.
In large families, clothes and other items get handed down. Both the giver and receiver learn to decrease their moh-maya and haumai regarding material things. And that's the basis of religion.
Our head should belong only to Sri Guru Granth Sahib ji, not a white devil hag who does not care about Sikhs at all and whose monarchy has attempted to destroy Sikhi and its people through countless war-crimes.
Many of us, including myself, in the west are guilty of adopting western thinking far too much to form and support our beliefs when we should try to make more effort in being simple and using only Guru ji as our source of knowledge and wisdom.
We can read about philosophers etc. and we do have to adapt to our surroundings so we do not become irrelevant in the world but there should be a limit because, at the moment, so many are unable to acknowledge let alone find this balance between work and personal life. There is too much conflation in thinking and it is taking us away from our goal.
