First of all, anyone who loves Libya would agree that Gaddafi has to go. The question is - what comes after Gaddafi? It is unacceptable that any member of his family or his cohorts suceeds him, but the history of other Arab countries tells us that this is most likely - unfortunately.
But let's say that all the regime is removed...how will Libya be governed? Will it be a "Liberal Democracy" with all that entails ie. immorality and total secularism? This means that there is NO place for religion in the governing of the country ie. a total separation of religion and politics. Are the proponents of "Democracy" prepared to enforce this? Are they prepared to devise their own penal code, marriage and divorce laws and inheritance laws that bear no resemblence to Islamic jurisdictions? If not, they are not being true to the ideals of western democracy.
A liberal democracy means you MUST allow the "free will" of all - adultery, homosexuality, gambling and drinking are all allowed. Do they want Libya to be exactly like the West with all its vices? Under NO circumstances can religion be brought into the law-making process - it is total 'ilmania. If these people want democracy they should explain and understand this, not claim Islam as their guiding force while pretending to have "true democracy" (like Mubarak in Egypt and Zain alabidin in Tunisia).
Is this really what the Libyan people want?
If the proponents of democracy believe that it will bring peace, they are misguided as there are many people who only want Shari'a law. How will this problem be resolved - a divided country or more opression? Shari'a tokenism won't be acceptable ie. Mahkama shar'iya or some quadis/muftis appointed here and there. Total Shari'a is the only option for true Muslims, the way Allah (swt) wants it.
