One of the problems with calling on Muslims as a group to condemn these actions is that what happens is they generally come out and say that the terrorists were not good Muslims or were acting against Islam. This is the same problem we get when our idiot politicians come out and repeat the Islam is the religion of peace mantra over and over.
The terrorists in Paris are as much Muslims as the KKK are Christians, each follow their own interpretation of what was written by dark age savages and barbarians in languages subject to difficulties in translation and following concepts that are, frankly, uncivilised by current standards.
I don't want Muslims to come out and endlessly repeat that these killers are not proper Muslims, that's part of the problem with a huge and growing schism within the entire Islamic faith. All that does is feed the paranoia, fear, hatred and inter sect violence that is tearing the Middle East apart and driving these attacks here. I don't want Muslims standing up and saying 'As a Muslim I' any more than I want Christians standing up and saying 'As a Christian I'.
I don't want people divided along religious lines any more than gender or race. Pushing people to self identify as a minority simply makes them more isolated than their Dark Age religious beliefs make them already and that leads to ghettos and terrorists in training.
I don't want anyone to stand up and condemn these attacks and atrocities because they follow some religion or another.
What I want is everyone who considers themselves to be civilised, to be part of a civilised nation and to share the ideals of freedom and democracy, to stand up and condemn tyranny, intolerance and terrorism.
Stand up for freedom of expression and freedom from tyranny because those are good things worthy of your support. Follow your religion in the privacy of your home or church, in public speak as a member of our society and civilisation.
