leave this person behind. Take a hukamnama at a local gurduwara as soon as possible (Guru Maharaj knows best).
When we take amrit we are dead to the world. Keep rehat. Get into contact with good sangat at local gurduwara. If he still bothers you or pphysically abuses then you need to learn how to stand for yourself. That is why it is so important to become shashterdhari or learn how to defend yourself, so you can stand for yourself and those who cannot stand for themselves. Doesn't this person have parents you can contact. If they were aware of what was happening, that might stop that trouble.
Chill, bro. Lol at your renaming of Jagsaw to Jagsaw Khan. I agree that Jagsaw is dangerously Islamophilic at times, but at other times I enjoy his musings.
He has a platform to post just in this one thread. What's the problem, really? He's quite well contained, anybody that wants to avoid him is easily able to do so.
