I really do not have a problem with people sitting on chairs. The simple solution is to elevate the Sri Guru Granth Sahib ji to a higher platform.
So what you couls have is a Church type configuration, with Bani in effect on a stage and Sangat on chairs at a lower level.
To my mind that is the point is it not, for Sikhs to show they are metaphorically lower than there Guru, so it matters not where they sit.
I fid this funny about Badal, but I really think this table chair business is a red herring. It diverts us. Just like the table and chair business is hogwah. People from the East have not right to impose their standards on the West, and in the same manner the West has no right to impose their standards on the East.
One has to look at historically why chairs were not used. Simple, most people could not afford them.
