Well until the end of 20th century "Islam played games with that subject" but now people are going to put breaks. 
On that Islamic interfaith marriage and the product of that matrimony 
"THE ZEBRAS",...    Only fools specially Pagan fools or  converted pagan fools ` don't understand that the Islamic  system is thoroughly constructed to expand the Mosques and dorms and Political Islam .  Unlike other faiths this aspect is very unique to Islam,  The rules are simple.  
Muslim men  can marry a non-Muslim women or Muslim women ..1.2..3..4.... and produce more Muslims.  In  the case of Muslim women,  they usually cannot marry a non-Muslim men,  If it happens
 (the odds are heavily loaded against them) then  "He Must convert into Islam before the marriage"  and children must be brought up under Islam.  So  everything perfectly  designed to expand the Islamic Empire. Joining Islam is fine but  we know the rules   of leaving  Islam.  It is wonderful  and fine  to start a Muslim community in so-called non-Muslim lands and grow your numbers, but don’t try  that on so-called  Muslim lands.    You will have this..

And that is  72 year old lady and that news is couple of days old  
Read all about herFools talk nonsense.  before you talk such things clean up the mess from silly books.. other wise get  rid of all them.  Any way they are filled with nonsense and some children stories..
