Like I said before, it is all perception
Punjabis are generally a far more open people compared to people in other states.
We tend to air our dirty laundry in public so it makes it look like we are perhaps more bigger drinkers than we think we are whereas people in other parts of India may do a lot more things on the sly and behind closed doors.
At least that may be the mpression I am getting.
Like we've said before, prior to colonisation, Sikhs didn't seem to have any issue using Indic motifs and iconography to illustrate points. Someone put it into people's heads that this makes them 'Hindoo' and then you had some weird reaction to that.
