Ianao,
if you do attend a KH you would find out that many of the people you'll meet are common folks. They're people struggling with the challenges everyone faces. Depending on your locality, you may or may not find those who're interested in doctrinal/organizational matters. Some (especially some of the older folks) see it as another religion; it's just church with all the attendant 'problems'. But I believe, you may find love, especially amongst the 'common folks'. Some of those in oversight positions will show genuine love.
As PLH said,
...arrive right at the start time. sit in the back and OBSERVE!
IMHO, it would be just fair to see things for yourself. Coupled with the things you've learnt from elsewhere, you just might have a somewhat balanced idea of what JWs are.
