I agree that religion itself isn't evil.
Religious experiences include a feeling of being loved, a feeling of unity... That is the feeling of God(s).
Now, next comes the advancement: Say: I've felt this. Oh, but surely, this cannot be something mundane, this is divine! So, I build myself a pantheon, with names for gods, and characteristics. But all the while using that feeling of love as my centrepiece.
Now, we've got religion.
(This is not to say that God does not exist, of course. But the Divine sends us a feeling, and we, as humans, simply make do with it. Eventually, every religion is written by human hands, but inspired by this feeling of the Divine. Something we cannot really understand, yet.)
So now come the followers. They claim the follow the Truth, with a capital T. Now, doctrine is written, and after that, dogma. And from here on, things get worse, and religion isn't what it used to be anymore. Suddenly, few people actually remember that first feeling. Or they turn it around; suddenly they claim this feeling of love is for them only, not something to pass on to everyone. And they are willing to pass the love, but only if you accept their truth.
Happily, not all religious people are like that. Far from it. But these are the loudest, the ones we hear from most, and the ones with the largest influence. And that's a shame, because religion, and religious practice, can be so beautiful.
