You also hate and fear the unknown.
Yes, I do. I am human.
That is why I often attempt to learn a bit about those things that I find worrisome.
That often helps. Sometimes, as with Islam, it helps by giving me a clear direction to pursue.
You hate Islam but you don't know it.
You don't know the history.
I have made a honest effort, to the point that it would be dishonest of me to claim ignorance now.
I also find myself consistently appalled and disappointed by the efforts of those who attempt to present Islam as honorable.
If there is a God, it is by now certain that he does not want me to support Islam.
When real Islam ruled, We invented the Algebra, Astronomy, the Zero, Moden Medicine basis like blood cycle, alchemistry ....
Not sure what you mean to say here.
There was certainly a time, long ago, when the Islamic World made impressive contributions to science. No argument there.
Where do you want to go from there?
Are you perhaps implying that the world would be far better if "real Islam" somehow "ruled again"?
Why exactly do the dozens of Muslim countries and about one and a half billion Muslims currently in existence do not count as "real Islam" then?
The Caliph was ruling many countries where non-Moslem were majority
That is a bit of an oversimplification, of course. But let's roll with it.
The Sharia sets churches and Christians free.
How so, and free from what?
Why specifically "churches and Christians"?
Does that freedom extends to, say, Druze, atheists, Buddhists or people who are simply not interested in having any specific religious label? If not, why?
How is Sharia any better for any given group or person than the alternatives?
As per Sharia laws, Non-Muslim are totally free to manage their own things independently, drinking, eating pigs although it's not allowed for Muslim.
That sure sounds nice, until we consider that this is insistence on a clear, permanent distinction between Muslims and non-Muslims.
The unavoidable result is a lot of sources of conflict, resentment and mistrust. To say nothing of the practical problems that it creates.
How independent can people be really when they happen to be living side-by-side? Or even when they are not?
The Muslim husband should take his non-Muslim wife to her religion house, by for her what is used in her religion
I take it you mean the house of worship, the temple of the wife's religion?
I am aware that Muslim men are allowed to marry Christian and Jewish women, for what it is worth.
and many many things that you don't know about Sharia
What of them? Feel free to mention anything that you think might be helpful in giving people a better understanding of Sharia.
If you know Sharia you would ask Muslims to practice it
Perhaps, although I find that unlikely.
