It is as elitist in my opinion to feel that anyone who doesn't agree with oneself is either crazy, silly or dangerous. People have been killing people for all sorts of crazy reasons throughout time. Religion can be used just like money or property.
I think that all things are paradoxical. Its too easy to say it has to go because there are bad people in the world who do hurtful things and use something as the justification of it. Being respectful doesn't just mean that you don't say to someone they are deranged or silly for religious belief, it means you don't assume they are deranged or silly for having belief. I agree with you that there are evil people that should be fought against. Thats not even close to a reasonable proportion of people with those beliefs. There is nothing silly about people feeling like something gives direction or purpose to their lives. As a parent there is a deep spiritual connection to my kids. To me when I saw the sunrise this morning took my puppy out for a walk the world was quiet and covered with snow. I knew that i wanted to post the pictures i took here on this thread as it was a moment i knew a connection with something bigger than myself that wasn't to comfort pain or make someone else feel small. it was just beauty
