Religion now is only useful as a crutch or prop for weak or needy people, and as such should be replaced with some new humanitarian support system for those in need. Most people do not need religion to tell them what is right and wrong, and don't need or believe in the threat of horrible punishment after death to influence their actions in the real world.http://www.humanism.org.uk/humanism
I thought I'd jump in and comment on the above.
But first - on the thread's topic, as others have pointed out, Islam's rules do not allow for a Muslim woman to marry a non-Muslim. This is one of the rules - there is wisdom behind the ruling, but at the end of the day it is what Muslim's believe are God's laws (this ruling is in the Quran).
I totally agree with all those who point out that Muslim women are oppressed in many Muslim countries - unfortunately this is despite the teachings of Islam, rather than because of them - in all cases the religion is being misused to reinforce external misogynistic customs - eg tribal, regional or even political (in the case of Saudi, for example).
Islam does discriminate between men and women - but only in matters that are directly related to their physical nature, in the same way (to take a trivial example) that say athletics discriminates between the sexes when it comes to competition.
Ok - back to the point about religion.
You may be surprised to read that I actually have a lot of sympathy for Speedhump's summary of what religion is today. Actually, I would go a bit further - for many it is not even a crutch, but just a historical/cultural set of rituals that one observes because everyone else is doing so, or the family does so. This goes for all the major religions - including Islam.
I see it in a historical context - all religions go through the same cycle. Compare the theocracies of Europe's Middle Ages and we see a lot of similarities in the theocracies of today's Muslim world - including misogyny (interesting that - hadn't thought about that until now !)
When religion loses meaning and becomes as Speedhump describes - just a loose crutch that also gives some moral values, I do think it offends the thinking person to follow it. It offends logic - as to follow a religion that is 'dead' is totally illogical.
However, whenever in the past the religion of the time has reached this moribund state, we have always seen a renewal of faith by 'revivalist' movements or messengers or guided leaders - Islam, Christianity, Hinduism all have their examples. What they all say they are doing is taking people back to the fundamentals and basics of each religion.
That said, the only litmus tests I have for a religious set of values (i.e. a religion) is that it a. is logical and b. provides the prospect of a two way communication with God.
a. It has to be logical, because if God created us, He created logic and would not ask us to believe something illogical.
b. God will not stop communicating with mankind just because some clerics say He has stopped - history shows us that it is normally the clerics who are most astray, and therefore be wary of any cleric who says 'only get to God through me' or 'pray to such and such and they'll get to God' etc. So my touch stone is that the religion must promise an affirmation of the religious practices direct from God (else you may as well pray to Bill Gates - for whatever good that will do you).
Just my 2 cents worth.
