Is religion the cause.....?

atheists are always so quick to point the finger at religion for causing suffering. they often bring up the inquisition and terrorism etc... they seem to have forgotten all the atrocities comitted by the atheist extremists under communism. in the soviet union religion was outlawed. millions of christians,muslims and jews were imprisoned or even killed simply for practicing their faiths. religious persecution still goes on today in china, north korea, vietnam and cuba. i dare say that the inquisition pales in comparison to the atrocities comitted by these atheist regimes. could it be that its not religion or atheism that cause all this suffering, but just arrogant human nature that says "im right and anyone who disagrees with me must be silenced" ?
