Aarya is not a name I've ever heard in the Sikh context, and it's probably not a name I would favor, but ... I don't know why we would have to reject it specifically on the basis that it refers in literal meaning to Durga. After all there are plenty of Sikhs named after Hindu gods/avatars: Ram Singh, Hari Singh. The latter was the name of the Sikh Kingdom's great general.
Not to even mention Guru Ram Dass ji, Guru Arjan Dev ji, Guru HarGobind ji, Guru Har Rai ji, Guru HarKrishan ji, and Guru Gobind Singh ji, all named after "Hindu" personages. Now if you say "Ram" is actually referring to God, OK, fine. But the same would also apply to all the other names given above, including Aarya.
Also, does Beethal refer to God, or a Maharashtrian demigod?
Why don't you just post the URL. It's difficult to know which one you are talking about.
If you want, then don't make the URL into a link (blue underlined text).
Rather, paste it into Notepad, and then lop off the first portion of the address and paste back into the SikhSangat post like this:
Then, there won't be a link to that video on the Internet.
I think the big problem with various jathas and sampardas is that they have forgotten their original founders' lifestyles and rehits/hukums and for what purpose those maryadas were for.
Nihangs: meant to be a perfect Sant/Sipahi force. Sad to see junkies and infiltrators in blue robes zonked out on the sides of streets.
AKJ: A minority have no clue about Bhai Randhir Singh Ji's teachings and books, and think they are a singing squad of missionaries.
Taksal: Many Taksal-oriented Sikhs desire for a return of the Bhindra Taksals to the original format as inspired by Sant Gurbachan Singh ji of Bhindran.
Missionaries: If they would read and follow the books by their spiritual grandfather, Principal Sahib Singh ji, they would not be doubting Guru Granth Sahib, Dasam Granth Sahib, or kakkars.
