There is something I have noticed different between Jehovahs Witnesses and mainstream religion that is mainstream religion allows members to go to other churches. You can visit and join then walk out and go to another one, it is okay! Where as a Kingdom Hall you get baptized and if you decide to visit another church you get disfellowshipped and marked for life! See the difference, any church that does not allow members to let you visit other churches, you should stay away from and do not go back because it is a cult!
And a theology professional shared that thought with me!
