Oh please, since when does anyone put any thought or consideration into other people's beliefs anymore.
Everybody tries to change things, but religions etc. were designed for control, control also means that you don't lose people, hence at the end of any religious text ever written it always states something like:
"This book is absolutely correct and if you disagree, bad stuff will happen."
"This is the last book, if anybody else comes along, they're lying."
''If you do not worship these beings, you will have your worst fears realised."
etc.
'Deconversion' is stupid, belief systems are evil in their highest power, even belief in nothing, if its a system, its not doing any good, its manipulating people.
The only problem is its a catch 22, even if you could just make everyone instantly stop attacking each other's ridiculous and outrageous beliefs, you'd just have the opposite extreme of everybody running amok.
