I think a secular Muslim is someone who can accept that the state itself is non-religious and rules on behalf of all religions, ethnics etc and does not put emphasis on one of those. Religion is private, thats my idea of a secular-Muslim.
What I didn't like is that there was no clear commitment from Zulkarneyn to democracy. He also argues in favor of Sharia which is not compatible with the our constitution or democracy.
I dont see what's the problem with secularism (generally; this is not directed at Zulkarneyn) , you can practice your religion as free as you want. The problem is very religious people will put their noses in the lifes of others: You cant do that, thats harram etc. ,these people they will put others under pressure for being different until they bend and do as they want or people get hurt.
I would also like to ask Zulkarneyn whether he thinks that Science (which you're apparently supporting) is compatible with religion.
Also Zulkarneyn if we introduce sharia-law for Muslim, Jewish laws for Jews etc which law will be used for non-religious people? Which law will be used if a Muslim steals something from a Christian? Chaos.
Quran reveals many interesting scientific phenomena that wouldn't have been known at the time; such as the expansion of universe, the seas whose water do not mix with each other, many others about celestial bodies, etc. This is amazing considering that the Quran was revealed in 7th century.
Islam obligates us and encourages us in the pursuit of knowledge as in "Seek knowledge even though it be in China."
How can such a religion be incompatible with science? Do we have an example of lets say... a proven scientific knowledge that is in clear conflict with Islam's teachings?
I think the Catholic Church's clashes with scientific community in middle ages as in Condemnations, Copernicus and Galileo affairs, etc brought this sticker that science is incompatible with religion.
Secondly, Islam is a comprehensive religion, its rulings cover all aspects of life, social, economical, political, judiciary,... Can not even pray certain prayers alone such as the Cuma prayer which requires a communion. It covers both private and public domains.
The choice of believing whatever he wants belongs to each individual. The choice is personal. One can choose Islam, be atheist, be a Christian, etc... There is no compulsion. However once we make the choice to be a Muslim, there is no longer an option for us anymore but to embrace all rulings of Allah. Otherwise, if we don't then it means there is contradiction in our belief.
How can we tell that we believe but at the same time reject Allah's rulings-laws or refrain from applying them? This is pretty much a mutually exclusive situation. One one hand declaring our faith in Allah, his Angels, his Books, his Prophets and his Destiny in its entirety but on the other hand rejecting or disliking application of His rulings.
Would there really be a good reasoning, an intellectual basis behind such a belief? What could be the possible rationale of a Muslim who does not want/like Sharia? We accept Allah as our Lord but do not recognize His authority? or that we know better? The society of men can develop better laws? or that His rulings did not last the elapsed time and are no longer applicable at present?
The people who do not rule by what Allah sent down are described as unbelievers, wrongdoers, and rebellious. Similarly believing in part of the book and disregarding the rest is not an option.
"... and whosoever does not judge by what Allah sent down, such are the disbelievers." (5:44)
"... and whosoever does not judge by what Allah sent down, such are the wrongdoers." (5:45)
"...and whosoever does not judge by what Allah sent down, such are the rebellious." (5:47)
Allah condemned the Jews saying: "....Then do you believe in part of the Book and disbelieve in part?" (2:85)
