" My focus is only on doctrine. "
Doctrines of Jehovah's Witnesses currently :
A generation is NOT 30-40 years, not 70 years but 150 or more years of multiple overlapping generations recognizing the " time of the end " which Jesus said " this generation will by no means pass away till these these occur, then the end will come. " So the " time of the end " will be as long as the WT Society wants to make it to keep getting converts.
If a Jehovah's Witness needs a blood transfusion they are not allowed to take whole blood transfusions to save their lives, only blood fractions and that's ONLY if a Christian's conscience allows it. If a minor child has Jehovah's Witness parents and needs a life-saving blood transfusion - these JW parents can choose to allow that child's death by forbidding a blood transfusion and will not be held accountable by WT appointed elders or the WT Society because it's a directive of the WT Society.
If you have a child who is molested sexually by a fellow adult JW - as a parent if you report it to your congregation elders they are instructed by the WT Society to call WT legal headquarters FIRST before EVER reporting the crime to police. Then they are told if they live in a reporting state or a non-reporting state and given instructions whether or not to report the crime. If police investigate or attorneys investigate the child abuse elders are instructed to have them contact the WT legal department first. Elders are instructed NOT to give any information to outsiders unless the wT legal department is involved. Thus the financial interests of WT Society are the priority- not protecting innocent childrens lives.
If you have a 18 year old child who wishes to attend college to further his or her education- WT elders are told by the WT Society to counsel you AGAINST sending your child to college to get an education. No " independent thinking " allowed outside of the WT organization. Talks are given at JW assemblies saying this and articles in the WT magazines. If you are an elder or Ministerial servant and your child starts attending college- you will be removed or asked to step down as serving in a position of elder or ministerial servant in the Jehovah's Witness organization.
So here are about 4 DOCTRINES that may have changed since you last attended in 1986.
You still want to support an organization like this ?
Your statement, " I don't believe the acts of some bad people determine it to be the truth or not " . Even if those " bad people " are the ones making doctrines that take peoples lives, foster child abuse, deceive people about Bible prophecy and prevent young people's education ? To each his own. But I'd think this through if I was you
