I am not angry as per se, I am sure other people on the forum will react the same way because this same topic shows up over and over again. Even people comment about it and then the original thread gets off topic.
Whenever we debate there is never a conclusion. The only conclusion is that the Khalsa Panth has accepted it as minimum. We should respect the opinion because when the Khalsa decides something as a whole, the Guru also decides it.
"Khalsa mera roop hai khaas"
It's anyones choice to be honest. If it's minimum then of course you are free to do longer. Anything shorter is not accepted.
