Desert Bird, honestly many of us don't write urdu on regular basis and have had very limited urdu writing experience in our lives so having spelling error is natural.
We all might be more fluent conversing verbally in urdu, as we all most likely converse in urdu on daily basis compared to writing urdu which is something we do once in a blue moon. If by our spelling or grammatical errors you think we don't feel pride in Pakistan or in Urdu language then you are hell wrong. If we had an inferiority complex about our language or country, we wouldn't even start this thread.
So I am going to politely request you to quit these derogatory comments.
