@reasoning logic,
In a civil society with freedoms respected, of course. But in a society highly oppressed by religion, likely there will be retribution in the form of targeted homicide on the individual converting or the individual's family.
The twisted nature of Muslim teaching, moreover, includes that a man is allowed to marry a Christian or a Jew with no problem, as long as the spouse is "devout" in their own perspective religion and does not have any bad intentions against Islam.
Then there is the potential for conflict as to which religion the child must be loyal to. Naturally
* it is the husband's religion, and women have no say on the matter.
It's all poppycock.
