It is not a whim
Yuyutsu,
So, if we go to the land of the Sikh & walk in with shoes on we'll be allowed to do so because in Australian culture this is acceptable ? Will someone from the Amazon where they chew & spit food into a bowl for others to eat be allowed into their kitchen ?

Dear Indyvidual,

I can't see the connection - you do not have a religious obligation to wear shoes, nor are the Amazonians religiously obliged to chew and spit into your bowl. You do in fact take off your shoes sometimes anyway and the Amazonian would probably find it a pleasant surprise if they came by well-cooked food that does not require pre-chewing and spitting to be ready.

A small ceremonial dagger that is encased in a hard metal box which cannot be easily opened, poses no danger to anyone, nor is unhygienic. I can see no reason for objecting to it other than spite.

Guide dogs for the blind are relatively more dangerous and unhygienic and yet many venues make exceptions for them where other dogs are not allowed.

Yuyutsu,
What's the point in carrying it then in Australia ? There's no cultural requirement for it here !

Dear Indyvidual,

There is indeed no point of "carrying it in Australia" - the only point is just "carrying it".

You happen to be in India - you carry it; You happen to be in China - you carry it; You happen to be up in a plane 30,000 feet high - you carry it; You happen to be in a submarine 3,000 feet low - you carry it; You happen to be in Australia - you carry it; You happen to be on the moon - you carry it...

You happen to like the feeling of carrying it - you carry it; it feels uncomfortable and heavy - you carry it too; the girls like you because of it - you carry it; the girls won't come near you because of it - you carry it too; carrying it makes you feel proud - you carry it; carrying it makes you feel embarrassed - you carry it too...

You carry it in summer, you carry it in winter, you carry it in autumn, you carry it in spring - you just carry it, all the time.

If God or the Guru said "carry this", then you carry this - you obey God and your Guru, wherever you are, whether you enjoy it or suffer it.
If "this" happens to be a dead mouse, then you carry a dead mouse, wherever you are.
In the case of Sikhs, "this" happens to be dagger - OK, so you carry a dagger.
In the case of Jews, "this" happens to be a zizith - OK, so you wear a zizith.

You respect God, you respect your Guru, you observe what they ordained and that is what makes it a religious point rather than just cultural. Wearing shoes or chewing and spitting food, on the other hand, are not ordained but only a matter of custom, convenience or whim, thus they are not on a par with the Sikh dagger.

Yuyutsu,
That sounds rather self-centred to me !

Talking about being self-centred?

Carrying a phone, wallet or a gun, can also
be considered as being "self-centred" by some.
While others consider these things as being
just tools and should be treated as such.

It all depends on the context in which they're
involved.
