My understanding of those radical muslims are that they get provoced to a degree that make them act out in voilence. I do not know, but maybe they feel their action is the only solution in todays society.
I believe non action would be better.
I'm sorry, but what you wrote above sounds like what an abuser says to try and excuse their abuse. I don't care what words or images a person might use to provoke their spouse, it can never rise to the degree where physical violence or murder is justified. Your words might provoke me, but they can never MAKE me react with violence... how I react to being provoked is 100% on me, no matter how hurtful I might find your words to be.
And we ALL have to hold people responsible for how they choose to react to mere words or images. Even if I completely understand why a group is upset by what someone said and would completely support them speaking out against what what said, I would NEVER condone them reacting with violence and would never excuse their violent behavior by suggestion that they were somehow MADE to react violently. We all have to stand up against radical violence, otherwise any group that decides it will react violently to anything said that offends them will effectively be able to silence the rest of society. It's the only way a free and civilized society can function.
