capsicum, almost every religion has people using that religion to justify their abuses of others. Should I mention the pedophilia running rampant in the Catholic church, including cover-ups at the highest level?
Even if the Pakistani community in the UK has a large problem with forced marriage and possibly forced underage marriage, that doesn't negate the fact that there are many Muslims who don't condone this practice and they are working with the UK legal system to protect children, men and women from this practice. It is very possible that in the future there will be no more forced underage marriages in the UK, Australia, US, Canada or wherever because there are laws and support systems available to protect children. The practice can be dramatically reduced, at least in first world countries. I doubt it will ever die out.
I have posted links that show examples from around the world and across various religions where forced underage marriage has occurred for various reasons primarily related to the family's honour, aligning families for business or political reasons, pawning off the care of a child to a spouse, especially an ill child. Religion is sometimes used as a justification when trying to coerce the children in marriage, but it is only secondary. The main reasons are usually one of those listed above.
It is very disturbing that the prophet Muhammed married and had se.x with a young girl. It sets a terrible example for Muslims while Allah apparently does not approve of such marriages. I'll leave that for Muslims to reconcile. People of other religions have their own things to reconcile in their inconsistent religious texts as well.
