British here.
I went to a Christian primary school in which we were taught about nothing but the teachings of Christianity. My secondary school's RE was on the big six religions. With an intense focus on Islam. They made a point of always avoiding any bloody undertones any religion ever had. Not once were we taught about an atrocity, or a war that involved religion. We were told that religious people were the most intelligent and gentlest people you will ever meet. And that they love everybody unconditionally.
As a result? I'm the most militant atheist to ever walk the Earth. Maybe RE does enlighten someone, in it's own way.
They never told us about the racism, the homophobia, the brain-washing, the Zionists, the hated, the wars, the crusades, the emancipation's, the massacres, the politics, the despair, the murder, the hindrances to human progress, the hindrances to human morality, the complete illusion freedom that the church claims to give us. It was taught that religion is an absolute good. Why? So that they don't offend anybody that may be religious...
Not one bad word was ever spoken about religion. Out of respect, maybe? Why should I respect a brain-washing bronze-aged mythology'd fascistic way of life, when it clearly doesn't even think about respecting me? And don't lecture me about the kindness that religion has bought. Do you seriously think that human kindness wouldn't exist without religion? It's kindness that will be there none the less, same with culture, and ways of life etc... Thank god Science was the period after RE on my timetable.
It makes me incredibly angry that religion is so respected...
