cannons firing explosive shells are not mere guns.

Riding horses didn't require to able to move that much.

This is inaccurate. Good armor was bullet-proof. People stopped wearing armor for other reasons.

A more than basic education is <2% of the population.

Not in the western world. (North America, Europe and Japan).

When was the last time you left your home ?

Very few of the people I know believe in god as depicted in the bible, even though a lot of them were baptised or married in a church, and are thus registered as christians.
Most of them haven't even ever read part of the bible.

From my personal experience, it's especially the case with people under 40 and even more so under 30. Additionally the more highly educated a person is the less likely he is to believe in god. I'm just inferring from that.

So are all religions which are proselytizing.

Islam is about dedicating your life to the worship of god, and following the law of god in everything you do.
Christianity (in modern times) is about loving and accepting others.

So I wouldn't exactly say that all religions are the same with regards to tolerance.

Christianity currently has about all of the most powerful countries on their side (with the exception of China), so Christianity can have a pretty laid back attitude right now.

Christianity barely exists at all. It's only a handful of old people around the world following the basic principles without any official government support.
In any case, they're not proselytizing any more. The religion is slowly dying out.
Good riddance. Two big religions to go still.

It's not "shaping up to be". Islam has always been about forcing the one true view of god to everyone.
It's by definition intolerant and bent on world domination.

I would love to see this magical oil the US has secured through war...

Thanks to war, the US now has very influential connections with the governments and the economies in the middle east.

Oh? The US doesn't use techniques like that

Shale oil is getting fairly important in the US but isn't properly government-controlled and has serious environmental impacts.
I don't suppose it is very publicized on TV.

That right there is the issue, because European countries are smaller, they are better able to build public transport. In the US, it just isn't possible. The major cities have metro rail systems, but you still have to drive your car to the nearest train station if you don't live in the city. The US is enormous, unless you have actually driven around in it, it is hard to imagine.

A public transport network, even a large-scale one, would end up cheaper than everyone having their own car, especially if having low fuel prices requires the government to take important and costly measures.
It's not going to happen though, because that would against the american way of promoting heavy consumption.

That kind of games is not primarily targeted at children.

Stop rethinking the classroom every other day.
All "classroom rethinkers" ever propose is distracting kids with useless technology.
