The questions here is not who should be excommunicated who not.The question is whether is their any concept of excommunication in sikhism?
well the historical reference clearly tell us that concept is in sikhism.
The issue that it is misused is different one.There are lot of things in sikhism that are misused[/quote]
The issue is well explained in Gurbani of Sri Guru Granth Sahib Ji.
We are advised to STAY AWAY/IGNORE..the SAKAT ..meaning an atheist, agnostic, cynic..etc..(one who is going to lead one astray and away from the path of Gurmatt/Akal Purakh/sikhi)...and IF one meets a SANT...a Holy man who is walking this Path of Gurmatt ..in that case we are advised to..Kichh sunneah..kicch kaheayh..Nanak !! Discuss..have a dialogue..talk..listen....
SO Since the Ram Raiyas..the MINAS..etc were directly competing with GURU SAHIB ( as the Namdharees/Nirankaris/Radha Soamis/Deras/Babas/Saadhs/) are DOING TODAY...and all these come under the definition of SAKAT !! ..and LEAD YOU AWAY FROM Sri Guru Granth Sahib Ji/GURMATT/TRUE PATH.
GENERAL DYER was bestowed a SIROPA and Robe of Honour at Akal Takhat...in modern times KPGill is being accorded the same treatment (BY NOT CONDEMNING HIM ) Prof GURMUKH SINGH was kicked out of Akal takhat becasue as a LOW CASTE he challenged the PUJAREES position.
Giani Ditt Singh who is fast becoming aFavourite of DG supporters wrote a CYNICAL PLAY about How his dearest friend and companion Prof Gurmukh Singh was treated by the religious Powers that be !! Prof Gurmukh Singh ji was NOT a RIVAL GURU..he was not starting a New Rival panth...so he is NOT in the same league as the ram Rai...minas..etc etc or the 22 gurus of Bakala.
THE Sri Guru Granth Sahib Ji is the supreme Akal Takhat. Any action has to be as per Sri Guru Granth Sahib Ji.
