Why has Canada not succumbed to either neoliberal fundamentalism, or fundamentalist Christianity in the same way the US has?

Hard to say. The stakes are lower in Canada from the point of view of those who think in terms of power, as Canada doesn't have the power that the US does.

However, fundamentalism has nothing to do with it. Guilt and learned helplessness are part of the christian experience with few exceptions. (I'll also reduce my use of the term "the church" to christianity. I don't know enough about any other religions to say either way.)

At some point you are just going to have to call it a day and accept that your measuring tool may not be perfect. The question is, is it good enough? Of course you can look at other tools as well. Some may in some ways make stronger statements than the Universal Declaration of Human Rights. One example would be the Canadian Charter of Rights and Freedoms. It, unlike the UDHR is quite explicit on the rights of Homosexuals. If you feel it important to examine the role of learned helplessness within Christianity, or any other religion, then do so. Don't limit yourself to religion, and do not fall into the trap of assuming one-size fits all. Personally I think that one can get unnecessarily complicated and loose sight of the forest for the trees.

Your assumption of a complete lack of nuance on my part is telling.

you are the media you consume.
