I didn't intend for that image to make my argument for me, it's just a neat example to help illustrate my point; using effective images is not off-bounds. It's not supposed to symbolize people "just talking" to each other, rather
the sharing of free information with each other in a highly effective and accessible way, and also allowing anonymous discussion of the topics at hand without having to worry about being socially outcast or, in previous times (and some countries still today), much worse.. In almost all of history, you couldn't bring up doubts about religion except in secret meetings or with very close friends, for fear of repercussion.
More images:
Sure there's a lot of people who are still saying "Praise Jesus" to each other, but as long as the internet is around, science, truth, and reason will always prevail, even though it might take a while for most humanity to snap out of it. We're changing and I really don't think religion is going to have much power at all in about 100 years.
In regard to backup, it's not a right/wrong thing -- I mean you're culturally Jewish, but I imagine you don't pray, go to temple, or worry about a deity on a daily basis. You are probably acting as Devil's advocate for those who are religious, but remember, they are not the ones who are oppressed, given they're a huge majority, so I don't know why you feel the need to stick up for them. If they're oppressed with anything, it's reason and logic, something nobody should be defending them from (and also the underlying thesis of aforementioned book)
