Hmmm Indeed a very important issue which u've brought up Sooli, (y) 
Before I may say anything on this issue, would just respond that knowing abt ur past and learning frm it is very important in order to do progress and bring some change in future. Therefore, it is of utmost importance to know about one's national identity as most of the social, economic, cultural and ethical development of any country depends on its national identity. This was to people who think that it makes no difference.
Now coming on this very debate which I would classify as the "Identity Crisis" of Pakistan, all of you have brought up some really good points and I do agree to most extent of all of your points. However, there is no wrong in being critical while analyzing the history and about believeing abt different versions of history. There is a famous saying that "history is alwayz written frm the point of view of the victorious people" and if we remark in syllabuses also, often one may find some biases in favour of that particular country.
Personally I believe that it can be great if we can blend these 2 idealogies together in a specific Pakistani context. The problem has been alwayz to consider these 2 idealogies as being completly dichatomous to each other which can perhaps be the case in western cases but not in Pakistan due to its blend of ethnic, religious, linguistic and cultural communities. In my personal view, perhaps that was what Jinnah also meant when using the words of "secularism". He did not mean it the western secularism in any sense but a more blended secularism of taking into full considertion of Islamic values and at the same time respecting all the rights of minorities also.
Now on the question of whether it was a "historic blunder" or a "pre-planned idea of a purely fundamentalist Islamic state", There can be argument on it. If we look back into the history and the documents from academic sources, one thing gets clear that the use of "Islamic identity" or the solgan of Islam was used in pre-independent era in order to get the wide support of all Muslims across India. Before religion, others symbols like language were also used but they were not that succesful, therefore the symbol of "muslim identity", and "muslim homeland" became that wide umbrella under which all Muslims were united. But, it was a temporary identity, which worked in the process of nation building and in the Independence movement but In my opinion, it was never to be the overarching Identity forever and history proved it in the case of Banglasdesh also that religion alone was not a sufficient glue to hold them together. The other identities needed also to be blendid in that like giving proper liguistic rights, having equal economic situations in which Pakistani Politicians absolutly failed and this is very cause due to which we r still facing many inter-ethnic/linguistic/sectarial problems.
Anyhow I guess its getting too long, but in short, if considered frm the idealogy of "Islamic state", then Jinnah wanted a modern Islamic state in which women wud have equal opportunities. If seen frm "Secular" point of view, then he wanted a blended secularism which wud be unique to Pakistanis and Pakistani ground realities.
Faiz ka aik sher yaad aa raha hay to wud finish it with that.
Yeh Daag daag Ujala, yeh shab gazeeda Sehar

Najaat-e-diida-o-dil kii Gharii Nah aaii
Chale Chalo ki Wo mannzil abhii nahii aaii
