A Believer, you're not baptized ALL OF US on here were. The stuff you're spouting out (or copy and pasting from JW.org) is old news to us. We know it. We studied it and believed it too at one time.
Your reasoning that "people laughed at Noah in his day and they laugh at the GB today..." doesn't hold water because we're told in the scriptures not to believe everything we hear. There's a sect in Russia were they all live in a commune and follow a long haired ex-USSR soldier who thinks he's Jesus. Everyone else laughs at them. Are they like the people of Noahs day? Are we to believe this Russian messiah is true simply because people are laughing at him? https://www.theguardian.com/artanddesign/gallery/2015/aug/19/russian-siberian-sect-vissarion-in-pictures
They too believe in an impeding disaster ( a global flood).
You're not baptized so you're knowledge is wayyyyyyyy below ours. You're talking to ex-circuit overseers, ex-elders, bethelites (some still active bethelites), ex-pioneers. The majority of us didnt committ any sin, we just wanted to leave.
Now, if you do choose to get baptized, you'll see that it's impossible to leave with your reputation in tact. We're here because we know what will happen when you get baptized. You're life wont be your own, nor will it be Gods... it will belong to 6 old men in Brooklyn with no theological training who, by their own admission, are uninspired and prone to error and who change their mind all the time. So WHY is their opinion any more valid any anyone elses?
