No matter how much religious radicalism can be spoken against, it continues to occur. Many religious texts are seen as life guidebooks, so before having the respect of others they need face scrutiny before being a respected frame of society (Or else any sort of teaching can potentially leak through).
If religious radicalism occurs, let exhibit A be the text in which that religion is said to follow, and let exhibit B be the crime done through religious radicalism. If exhibit A agrees with exhibit B the religious text should be...
1-Banned down to just a couple reference copies
or/and
2-Edited to no longer support the travesty
3-Illegal to proclaim as a life guidebook
Freedom of religion is fine, but freedom from religion need also be respected in a way that is respectful of human rights.
