That's naive. Evangelicals weren't concerned about abortion at all until the late 70s. They weren't as fanatical or rabid prior the rise of televangelism either.
My point is this. The current veneer of evangelism was a long time in the making and there were a lot of events and elements that got it where they are today, most of which were propaganda and politics. The modern Evangelical movements is mostly attributed to Billy Graham but the original philosophical offshoot was the brain child of a woman who was believed to be LGBTQ. He didn't come up with it himself. He learned it, and then he started warping it to line his pockets. Other like men followed suit. Rage pays very well, just not usually to the person who is enraged.
See how far they've shifted?
The same dynamic can happen to any group, irregardless of religion. I grant you, it's probably more likely to happen in religions.
The UK has a lot of extremist groups already and even more that are pacifists and have good intentions now but could easily shift under a charismatic leader and effective propaganda.
It's a slow burn, until it's not.
None of us are ever safe from oppressors and authoritarians.
Keep a weather eye, and keep your head on a swivel.
Our mistake was thinking the broader Christian community would correct their own when one got too far away from the core ideology. We were naive to think Christians actually care about the teachings of Jesus. Turns out, they don't. They just want to be part of the in crowd club.
