You sound like the biggest hypocrite ever on this forum. "I'd avoid such idiotic places". So basically what you've said there is that you'd avoid a place where Dhan Dhan Satguru Sri Guru Granth Sahib is present and where the whole sangat is powerfully japping naam which is the most important thing that Gurbani encourages again and again. Good job on proving what a manmukh you are. Only a true fool would agree with what you said and take you seriously.
"if they don't follow it then they shall perish". Does Gurbani allow you to do nindia? Especially of Gurmukhs who are always doing Naam especially daily in the sangat? Or even of a Gurdwara? Well no wonder you're such a fool as you're not following Gurbani, and therefore you shall PERISH. I'd like to see you argue your way out of this one. It's shocking to even think how someone can sit behind a computer and talk all this crap lol, about a Gurdwara, about the sangat and about Gurmukhs who want to meet God and reach God by following Gurbani practically, as this is the Gurdwara's only focus, to get you to meet God.
But the Manmukhs like you who wish to stay in the narak and not meet God will just keep doing the nindia and looking at the bad. If you are an amritdhari singh then I truly feel sorry for you and find it hard to take anything you say seriously. The user who gave your comment a thumbs up is just as bad as manmukh himself. The fact if you or him or anyone even tries to argue or defend yourselves truly shows how much you fail when it comes to spirituality in Sikhi as Gurbani and Guru Ji himself would clearly condemn everything you say.
If Guru Nanak Dev Ji was sitting somewhere in his physical form and the sangat around him was doing Simran loud would you call that an idiotic place? That's exactly what you've just said in your post. That clearly defines you a manmukh.
