No one asked for "a falsifier." Wrong can mean false but it can also be the opposite of right.
Like many born-ins, my shelf got filled slowly over the course of decades.
As a kid, I saw a relative tossed aside as a Bible study because he couldn't quit smoking at the rate his conductor wanted him to.
Also as a kid, I saw many people leave the borg because of the false promises of 1975.
Later, as an adult, I saw the tax-dodge change to the donation work lyingly described from the platform as a loving arrangement from Jehovah so that poor people could get the literature.
Shortly thereafter, I saw them change the meaning of "generation" again.
Then they decided to change the stand on blood into the confused unscientific mess it is today.
Then I was told I was overly proud for questioning elders about their incomprehensible decisions because they are "stars" in Jesus' right hand.
Somewhere in all that was the change from the literal heart as the seat of motivation to a figurative one, the allowance of organ transplants rather than disfellowshipping for it, and a few college courses that included some basic psychology and sociology.
I knew enough elders my entire life to never believe they had any direction or direct appointment by Holy Spirit. I never bought into the infallibility of the channel, though I used to believe God used the borg in a way he only understood.
I'm honestly not sure what the last straw is/was, or that it matters. The entire pile of crap has crashed to the ground.
