As most of you know, I believe ALL religions are as bad as one another.

I slightly disagree with this... I think some are worse then others.  It's difficult to measure Catholicism vs Dubism though.  On an individual basis, I'd say the negative effects of being a jw are far worse then the negative effects of being a catholic.  But there's waaaay more catholics then jws in the world, so simple arbitrary statements like 'don't use birth control' can easily lead to the death of an entire continent.

There's strong similarites between modern jdubs and the catholics of the 15th century (or earlier).  Jdubs are completely intolerant of any new ideas.  At least now catholics accept evolution.  (which renders the whole bible meaningless if adam never existed, but somehow they miss that)  

Within a modern context I'd say jdubism is more comparable to islam then most other mainstream religions.  (that would be an interesting topic)

Among all religions altogether, of course it has more in common with mormonism, mooneys, scientologies, any of the high control groups.
