Not at all comatose, all our opinions are legit.
I would add, contrary to what others say (sorry), I again would not try to imply that hawking Watchtowers and spreading indoctrination from the platform is voluntary work. Neither is helping carry bricks in the building of indoctrinatiin centres.
Voluntary work has the implication of doing aid work. Choosing to be a JW and all that involves is indeed voluntary and indeed work, but in no way is it offering aid to the community.
If you use that term, be prepared to explain what you mean by it. If there are interviews they will ask. Somehow through watchtower articles and personal stories within literature, the JW's had a belief that they can refer to their religious activities as voluntary work, totally misunderstanding that other religions do 'voluntary work' such as soup kitchens, helping the homeless, providing financisl charity aid etc etc.
As a JW i knew it was a cheeky thing to imply on a CV etc and I have no doubt you know what I mean by that. Academics aren't silly, they will expect to hear stories of feeding the homeless or mountain walking for cancer research, not handing out leaflets or building the property portfolio for Watchtower.
Again......just my humble opinion.
P.s. jobs where public speaking and sales are central, arguably mentioning the JW skills may be beneficial obviously. For me, I think the downside of being attached to the belief system far outweighs the benefit. I want to start teaching medicine in university and have already begun teaching on the wards and clinical skills department, but I have not and would not ever mention the 20years of bible studying I did.
