Wrong motives is exactly right , one foot in the hall and one foot out, we use to call these folks fence sitters.
Not only do they lack truthfulness in ideology , they may even financially support the WTS. which may be even a bigger crime.
I found most character profiles of most JWS to be very weak in the honesty and integrity department, it seemed if they made the
showing on Sunday they their covered with righteous purification for the rest of the week.
Call it being disingenuous are what ever, it stems down to hypocrisy and apathy toward what they really are supporting and holding up.
