It may be comforting to these people to equate "religion" with "fundamentalism" and secularism with "freedom", but REAL freedom involves allowing people to profess their beliefs, and to act on those beliefs, without interference or intolerance. It certainly cannot be denied that a lot of "religious" people have been involved in violence, and as the article from which that quote was taken says, Hitler was NOT an atheist - but Stalin was, at least for a time, a confirmed atheist, and Communism itself is predicated on the idea that there is no God. Not only that, but just as anyone who believes in God has to confront the problem of evil, so anyone who believes that religion should be banned "because it leads to violence" needs to explain why they do not therefore advocate the banning of politics, or soccer, or cigarettes.
In George Orwell's 1984, it was stated, "Who controls the past controls the future, who controls the present controls the past." Who is going to control the present-fundamentalism or freedom?
There is nothing wrong with atheism, but it will never "catch on" with religious people unless atheists can show that they really ARE "more ethical" than the religious (not to mention, unless they can prove there is no God; what we have to date is not proof; like the belief in the existence of God, it is no more than opinion.)
