I'd go so far as to say that organized religion IS a problem because it is usually evangelical, which means spreading the word of your brand of belief to convert the unbelievers. Now this doesn't apply always and to everyone but you can look even at modern Christianity and how it still lobbies from the pulpit on social issues, especially those surrounding homosexuality and reproductive rights (never mind the Islamic states that operate under Sharia). I also tend to differentiate between religion and personal belief, because although they are sides to the same coin, one is more personal and one is institutional.
I know some people will object to this thought but I believe organized religion is by its very nature politcal, it can't help but be that way because you have a group of people and need a power structure... and someone will always want to be that leader and have things interpreted according to their values and understanding.
You're right when you say organized (denominational) religion.
