We should never befriend muslims as they will end up burning you. Be civil with them at work and school but never get too close. Conversion is always on their minds, even the less religious ones will try to convert you.
Look at what muslims have done to us throughout history - Killed and fought against several of our gurus, massacred our people in Rawalpindi when they wanted Pakistan to be formed, attacking our girls with grooming gangs and just 6 weeks ago they massacred 30 Sikhs in a Gurdwara in Afghanistan.
They have always been the aggressors with us, I can't think of any time when Sikhs have started trouble with muslims unprovoked.
Instead of befriending them we need to retaliate against them when they attack us. I really rate the Sikhs of 1947 who were outnumbered 4 to 1 by muslims in pre partition Punjab, they managed to inflict far more casualties on the muslims than we suffered. Sikhs back then retaliated with ferocity. Today's Sikhs are too busy building mosques for them in Punjab. We should have done something to get even for the Afghanistan gurdwara attack instead of meekly complaining. Once the Coronavirus outbreak is over our idiotic leaders in Delhi will go back to giving langar to their protestors.
We should never give them support for Kashmir, it makes me very angry when I see some Sikhs marching alongside them at some pro kashmir rally. Let them fight their own battles and we can fight out own.
