I guess Moses Israel was idolatry and a cult? Being a cult doesn’t make an organization bad. Being idolatrous and occult makes it bad. In fact, your definition means all prophets of Israel and Apostles of Jesus Christ were idolatrous and occults.
JWs don’t blindly follow their leaders any more than the LDS Church members do. There are issues with JWs like shunning family who don’t want to be a part of their faith. Or, they’re bad interpretations of the scriptures and not knowing the true Jesus Christ. But, I don’t see them pushing Jim Jones stuff and by suggesting they are just like them is bearing false witness against your neighbors.
I banter back and forth with others discussing doctrine. But calling someone a Jim Jones because you don’t agree with them is over the top and unChristian.
