Re: Why can’t you criticise
because then you lose direction!
But seriously, we have treated Quaid-e-Azam and Iqbal like we treated our religion.
We consider them sacred but everyone interprets whatever they said in a way that suits his/her agenda.
Jinnah changed his political ideas a few times. You can find several conflicting ideas from what he said over his political career. Everyone can find a snippet of what he said to support his/her arguments.
Although I haven’t read much of Iqbal but I have heard/read from several sources that his earlier poetry conflicts ideologically with his poetry in later part of his life. The ideas in his Persian poetry are different from his ideas in Urdu poetry.
Short story: everything they said/did should not be considered beyond criticism. And if you criticize something they said or did, you are not disrespecting the person, but just expressing an opinion over those words or actions.
