I'd assume that the founders of Pakistan were not aware to what extent secularism would be instilled in India because there are Hindu nationalist parties that take every opportunity to target Muslim groups and organizations but are mostly rejected because their rhetoric is not favourable to secularism. It is secularism in India that has allowed Muslims to live in relative peace by the grace of Allah . But in spite of all this, there is always the spectre of Hindu nationalism in India, while the same cannot be said of Pakistan, which is, despite all its faults, a refuge for Muslims.
