What is so bad about religion?

There are two points of conversation almost all people want to avoid, well, at least the ones that are trying to make friends: politics and religion. I can write about both, but hardly talk openly about either.
Yes, religion is a personal matter, but what you believe about God and life is what makes you who you are. Some believe in nothing, some don't care, some can't believe in anything, some hate the category they would be put in if they believed something, some actually believe in something, some don't care what they believe as long as they a different than everyone else, some don't want to believe anything for fear of additional work, and some gave up believing in anything. What you believe instantly sets a standard by which you live. And it is your privilege to act according to your belief. That is one of the beautiful things that makes America great. You cannot expect someone else with a different belief or even a different understanding to act the way you do. With that said, however, there is a slight catch to the Christian belief that drives everyone insane. Once you belief in Christ, you want to and, to a degree, are required to give others an opportunity to believe in Christ also. So basically, there are a bunch of well-meaning Christians out there who want to give others an opportunity to know God in the way they know. Tack on the fact that everyone has both a varying levels of understanding as well as different points of doctrine, and you have a difficult jungle to weave through while talking about religion.
Here is my opinion, discussion of religion can lead to confusion and frustration or greater clarity. So get out and have a discussion (discussion occurs when at least two people interact in an exploration of a subject) about religion, the conversation will go three ways, one doesn't want to talk about it (queue to change topics), you will become more confused, or you might both just learn something.
But for all those preachy types, remember, no one was ever forced/pushed into heaven.
