I was never a baptized witness, but I do have plenty of experience with other churches and the kh's to form an opinion. And hands down, every other church I have ever attended is so much better than kingdom hall/jw worship.
I was raised attending Christian churches. The youth groups were amazing. We raised money to feed the poor, went on missions trips to help build schools, supported missionairies, at one point I was part of a traveling play that raised money for a missions trip. I didn't get judged if I went to another denomination such as baptist or methodist, not even when I started going to kh was I judged. There was fun, community, love, support, and true charity.
All groups of people will have people with issues, or more eccentric, or crazy, or....whatever. But I feel so bad for those who think church is a place of sin and false worship because of the lies told from the tower.
