Traveling around giving aid / langar to non-sikhs
If non-Sikhs are going around serving food to homeless and vulnerable Sikhs, there are going to be Sikhs that are going to be compelled to do the same.
Not having well armed sewadaar guards of Gurdwara's.
May prove problematic as in theory, Gurdwaras are supposed to be open for all. That will be the argument against what you are proposing.
Sikhs of sarbat da bhulla mindset.
There needs to be a better more clear understanding as to what this entails.
Not having our own sovereign state nation. To conduct our own economic, military, religious and political affairs
This perhaps is the most important point.
Inter-faith marriages and lack of promotion of inter-caste or inter-race Sikh marriages
Will meet great resistance from certain quarters but this is changing. If you are having arranged marriage then what you are proposing won't happen. If you marry out out of your own choice there is more likelihood.
A renowned lecturer and researcher in child development and abuse once told me that pedos frequently and consciously work themselves into positions of authority and trust to access people. I think they congregate and protect each other from such places. I think subtly exhibiting the deviant behaviour (or an indifference to it) lets the powerful ones recognise the upcoming ones, which they then fast track. It explains a lot. I think they recognise each other in various subtle ways.
There is something about 'pristine looks' with many gay men. Their grooming and dress sense often seems to be strangely impeccable and symmetrical. They are perfectionists with it. But saying that, there are some rough and ready as hell Panjabi bis/gays(?) who don't have that preening thing going on. Same with some working class goray gays.
It's weird how some are camp and some aren't remotely. With the camp ones, what's up with the walk and high pitched voice? Is it some biological thing? All that strutting and mincing. And the exaggerated gesticulation?
