You're making a fundamental mistake that child marriages, wife beating, beheading (capital punishment) are associated only with Islam.
How old was Mary when she gave birth to Jesus?
How old were Romeo and Juliet? Better examples please.
Child marriage is not a criminal offence in countries that it is allowed.
Also, you mistakenly assume that sexual consummation accompanies those marriages immediately. Only in some countries and some customs assume that.
Capital Punishment is not the monopoly of Islam.
Wife beating takes place throughout the world.
It's like arguing that all Catholics are terrorists. Or that the IRA are devout Catholics and a good example of Catholicism.
Mary and Jesus was fictional - no proof.
Romeo and Juliet was fictional. These are not examples.
Child marriage should be made a criminal offense, most countries have learned that it isn't and shouldn't be acceptable. Just because it's legal in some backward or developing countries doesn't make it correct. Children should be protected and allowed a childhood.
Sex with child marriage - rubbish. Childhood pregnancy is a bad, it happens commonly and can create health problems.
Capital punishment in a few parts of the world, but are all those people afforded a fair trial? Also, how many religions allow summary execution for an extramarital affair for example?
Wife beatings do take place throughout the word but this does not make it ok. Women are not possessions to be beaten and abused at will, nor, through the name of religion, should this be acceptable. It is with Islam.
I was born in the Middle East and we lived in 3 Muslim countries. Believe me, women are seen as possessions, nothing more.
