A few things...
First off, it seems like most, if not all the posts in this thread, are criticizing whoever is criticizing other communities.

So, why the hoopla?
Calling something bad, that is indeed bad, doesn't make the caller bad. The thread stays, no matter how useless some people think it may be! In fact, a thread like this actually shows that most Jats are not narrow-minded bigots and reflects us in positive light in front of others.
Secondly, whenever I see a situation like this, I am reminded of the famous Akbar-Birbal folk tale: How do you make a line short? Either you can try to erase it or you can draw a longer line next to it. Erasing something is similar to criticizing other communities and is not beneficial for anyone. Instead we should try to draw our line longer by making our community better and others will automatically be left behind, maybe even learn from us and try to improve.
Finally, I see that recently a lot of members have started "suggesting" to close various threads. It is absolutely hilarious that some of the same members were the ones screaming at moderators when threads were indeed being closed more often. Just goes to show that you can never make everyone happy! Again, someone has suggested that quality members have all left Jatland. I guess you aren't a quality member eh, writing nonsense all over the place?

Remember by writing this, you are not just insulting yourself but everyone else who is writing posts!
Personally, I would appreciate if you have a grievance against a thread that you send a PM to any moderator with its link and reason on why you would like to see it closed or deleted. There is a "report post" feature made especially for this reason.
