Spnadmin ji and Jasbir ji
I think the confusion / overthinking comes thusly:
1. many, many people have their ears pierced, including Sikh women
2. the SRM says "no piercing for wearing ornaments"
3. people thus pierced wonder why
4. they discover it was in relation to yogis/various other groups wearing them as part of their religion
5. the pierced people today think "well my piercings are just for looks / because I like them, they're not for religion, so why can't I keep them / get pierced in the first place?"
It is almost a case of the SRM having said no piercing, end of story.
Just like the DG prayers. That's what the SRM specifies for Sikhs, so accept it until it's changed.
So, to help justify in the mind of Sikhs who think their piercing has nothing to do with any other religion and can't possibly be anti-Sikh in that context, they reach out for other reasons to justify their action. Otherwise it's just blind following because the SRM says so, and I think THAT is more anti-gurmat (following blindly what the leaders say).
So if we can generate some more reasons why we shouldn't have our ears pierced, it gives more reason to follow the rules, gives people more confidence in their antisocial choice to not wear their earrings.
If I take them out now, and my colleagues say "Ishna, why have you taken your earrings out??" the conversation might go something like this:
"Why have you taken your earrings out, they looked good on you!"
"It's against my religion"
"Why?"
"Because I'm not supposed to look like a nath yogi"
"What's a nath yogi?"
And I'm left looking like a fool.
If I can find other reasons, the conversation might go like this:
"Why have you taken your earrings out, they looked good on you!"
"It's against my religion"
"Why?"
"Because they are a distraction to me, reminding me more about how my body looks to other people than how the divine in me looks to other people."
Just an example, probably a poor one.
But you've got to have strong conviction behind your actions, especially when it's against something as apparently benign and societal as dainty feminine ear piercings.
