Firstly, you have a problem with the language being used? What to do call a teacher? Ustaad (in Arabic/Islamic traditions), Aachaarya (in Bhaaratya/Hindu traditions) or Gurdev (in Panjabi/Sikh traditions). Maybe you'd like to police the language we use? Honestly, if you're that triggered by the type of language used, I'd dread to think what would happen to you if you came across someone who's name was actually "Gurdev"! A public forum probably isn't the place for you.
I don't mind answering any point you've made regarding Nidar Singh (in fact, I'd invite you to ask), but I do not want to derail this thread. However, I will say this. As much as you slate Gurdev Nidar Singh Ji, he was one of the few/only people who stood behind the victims of Sukhas abuse. What does that tell you?
And if you are going to reply, please come back with something conducive to this thread that would help support the victims of Sukhas abuse. Otherwise, please do not derail this thread, start a new one, and I'll see you there...
