What stands out for me is how many people in the world follow either Christianity or Islam. It is enormous and judging by predicted trends, these two Abrahamic Faiths are set to be the religions followed by two thirds of the worlds inhabitants by the end of this century.
Modernity has certainly caused a decline in Christianity where I live as the numbers of agnostics/atheists/don't knows/don't cares are set to eclipse the number of Christians. Then again, our population isn't growing except by immigration, and so we are seeing rapidly rising numbers of Hindus, Muslims, and Buddhists. We need to be more adept at diversity and multiculturalism. If we achieve this, then our lives have the potential to be greatly enriched.
The world wide trend for Hindus and Buddhists is continued decline in overall proportion of the world population and combined they will make up less than 20% of the population by 2060.
My wife's mother is from Japan and so from a Buddhist/Shinto background. I see many similarities between the values of Japan and New Zealand where I live. There are significant differences for certain, but much more similarities IMHO. I'm sure this topic of comparing the Dharmic Faiths to Abrahamics has done the rounds on RF. Its off topic in regards the OP for now.
I've had many conversations of the JWs here. I'm from a Christian background so know the bible reasonably well which helps to understand where they are coming from.
So back to the OP.
Does Islam need reform? I think your answer is definitely.
Is Islam too far gone and incapable of reforming itself? I suspect your answer to the that question is a resounding yes.
Is the Baha'i Faith a reform movement within Islam? I've already answered that question with my first post in this thread. I don't know how it plays out in Muslim countries other than there are amazing Baha'is that continue to practice their faith despite hostility from conservative and fanatical Muslims. I don't see the Baha'is trying to reform Islam but to be good citizens of their respective countries and provide a new vision of faith that incorporates both Baha'u'llah's revelation and Muhammad's. That's not easy. In the West, its the same conversation but with Christians and atheists. We generally say little about Islam because we're not Muslims and nor are our fellow citizens. Same deal in the East with Buddhists and Hindus.
