True. Radical "Christians" are no different or less savage as bloodthirsty murderers than radical Hindus or radical Muslims or radical Jews or radical anyone else - and murder and terrorism has been done in the name of every single one of those. Every single one - and the difference to the victims was zero.
All it takes is the right political or economic circumstances, and you can "radicalize" any of them. Without exception.
I don't care who claims to have first taught the "golden rule" of treat others as you'd be treated, I look at who's actually practicing it. That's what counts.
The irony is, you can find this basic simple idea buried inside of probably all of them too.
