Welcome Harsh and what a way to start!
In the U.S. one myth is that working lines are immune to hip dysplasia and do not have genetic problems.
I don't care if someone gets a WL or SL it doesn't affect me personally, but what bothers me is if someone makes such a decision based on a total falsehood. To me that's not helping the person who is trying to make a very important decision on selecting a dog that will be with them for many years.
So every once and awhile I'll chime in and try to at least correct that general myth.
I hope this thread stays positive, you may have to put some effort into moderating it yourself.
