You can't really fault this appraisal of the situation. The Anand Karaj (and related activities at the Gurughar) HAS become a ritual to quickly get out of the way before the "good stuff".
What must happen is the approach taken must not cause divides (or if divides are created then they must not be allowed to deepen), because I'm sure we can all appreciate that those trying to do the right thing will be made out to be the villains whilst those doing the beadbi will paint themselves as the aggrieved.
I would also like to point out that in some Gurughars in Panjab (official Ithaasik Gurughars and not one's built by villagers - not that there's any distinction from a shardaa perspective but I thought I'd make it clear before going on) there's a similar "production line" mentality where one Anand Karaj takes place, the Granthi rattles through the laava, does an Ardaas, and then another couple is ushered in for their Anand Karaj. It's an absolute joke, and even more shocking because you would never expect this approach back home.
But our attention, in regards to this particular issue, must be focused on the places we live.
EDIT: One thing I'd like to highlight is that not all non-Gursikhs (be they male or female) are hedonistic, party-craving lafungeh. We must be careful these types of people aren't lumped in with those who think the Anand Karaj is a ritual to please the elders of the family. If anything, they must be taken on-side and explained why things need to change. You'd be surprised if you approach such people in a respectful and sensible manner how much they'll take on-board and serve to perpetuate the message we are wishing to enshrine in the minds of Sikhs regarding how seriously we should view the Anand Karaj.
Remember, not all people are purposefully ignorant; some are simply unaware. Let's not assume things without facts. Use the wisdom and foresight that our Gurus and other great Sikhs were renowned for.
