That is true - but we need to expect that many who would teach at local gurdwāre, at the moment are probably not as knowledgeable as the people who are in the camps.
Definitely.
As do I, as do I!
Having a place to visit the Gurū is great, but education is needed too - about history, philosophy, theology, and why certain things are rejected, or practices the Gurūs oppose may grow, and I fear this is a possibility. For example, I've once visited gurdwārā to be greeted with someone nearby: "*tut* Gora [vich? I forget this word] gurdwara? Gore sikhi nahi." My very limited Punjabi meant I understood what was being said. The person who said it was rather young, though. To be honest, I found it quite humorous but it got me wondering if such views could grow, because I've had two such cases - both were young though, so I'm hoping they will grow out of it.
I've seen gurdwāre can often become almost segregated, not by gender or race, but people stop talking and become involved in petty squabbles, and you can sometimes find "jatt" and "khatri" gurdwāre
I feel such things need to be remedied before we can teach in them. I think a start is making a more social environment: langar is for that, but many feel as though you cannot stay in there too long. So, we end up seeing people talking in the main entrance instead... perhaps an additional room would be useful, one where people can stay and chat so there are not thirty aunties standing next to radiators?
