The birth place of Urdu is Delhi. Don't really understand why Pakistanis should be ashamed of this?
Plus Urdu is a Lashkari language. Urdu contains approximately 70% Farsi and the rest being a mix of Arabic, Turkish and Sanskrit, none of them are native Pakistani languages.
Right!
So we shouldn't feel ashamed. Though i can see the point the threadstarter is trying to make is not of the language itself but the fact that Pakistanis couldn't even develop a language software, especially considering that Pakistan's national language is Urdu; whereas, India's national language is Hindi.
Although Hindi and Urdu have some spoken similarities.
