Is willingness to discuss an indication of radicalization?

Could it be said that one could be radically adherent to an ideology or domain of thought which is, itself, composed of reasonable ideas?

Can one be radical for reason? Or is the aspect of radical behaviour one which is sought out of unreasonable thinking?

Is it ever reasonable to be radical? What is the problem with being a reasonable radical thinker?

# What is it to be radical?

Radical behaviour is one which goes against the fundamental norms of a system.

A good example of where this might be seen as a reasonable gesture is if one is operating in a system which imposes cruel constraints on the entities contained within it, and that the rationale(s) for such impositions are understood to be indefensible. What would make it indefensible?

Well it would have to be indefensible because those performing the deliberation a rationale share a position, perception or understanding for which the rationale becomes difficult to defend. For example, the rationale might be to kill all of those performing the deliberation. There is automatically a problem with this proposition, because it invites immense bias into the evaluation.
