There's some pros to be fair. While I no longer agree with all of the WT's doctrines, their literature is simple enough to assist someone in grasping a basic and working knowledge of what's in the Bible. Granted the literature has a hidden agenda, but it is simplified enough for the individual who is completely unfamiliar with the Bible.
I like being indifferent to holidays as it saves me money and unnecessary aggravation. I don't feel as if I'm missing out on anything by not participating in holidays and I have a small measure of gratitude towards to the WT for that.
The political neutrality as taught by the WT has some flaws to be sure. However I like the fact that when one wakes up to the WT's nonsense, they can take a fresh new to politics and non-biased view towards political and social issues as opposed to being raised Lefty or Righty. As a born in dub, I don't feel any connection towards Dems or Repubs, matter fact I hate all of them equally. For that as well I feel some gratitude towards the WT.
