Any informed or educated person that believes in any theist religion is either choosing to delude themselves or is incapable of processing information.
Any person that teaches or preaches about any theist religion in any way is someone with serious mental health issues in urgent need of anti-psychotic medication. I reserve a special place in the most remote insane asylum for any scientist that believes in any religion.
It is usually much easier to understand the events in Paris, Belfast, Israel, Iraq, Syria, etc, etc in this context. The human brain is a machine that is still evolving.
Theist religion was invented to explain the (then) inexplicable and create a means to control people. Neither are necessary any more.
Ridiculing any and all religions is essential to human development and any attempt to suppress this is futile. In fact, every attack on the right to ridicule and challenge religion is a positive thing. It simply wakes more people up to what religion is and does and recruits more to our inevitable anti-theist future.
Killing a bunch of mainly old people that create cartoons in France is so utterly insane that it can only be properly processed by me like this. France is one of the more advances countries, being mainly secular. It is disappointingly more so than our own country in this respect. However, given the advancement of science and information over the last century, I only give theists another century or so or murdering and violence before they are finally marginalised from humanity. The day will come when churches, synagogues and mosques are closed and bulldozed as frequently as pubs have been over the last few years.
