It is just when I see many (not all) posters and ex JW’s curse, I wonder is this how I am going to end up like after I leave.
If/when you leave, you'll only do what feels right to you. I had similar objection upon my first perusal of this site, but realized that it's just people being who they are, and everyone has different values and reacts differently to "waking up" to the truth about 'the truth.' Please remember, too, that many folks here have been visciously and irreprably injured by the policies of the watchtower society. Many have lost loved ones due to the (unscriptural) blood doctrine, some have been molested and had their attacker defended and covered up by the society. A large portion here have also lost loved ones to the unscriptural and painful practice of shunning. All this (and more) can understandably cause a great deal of anger and resentment that sometimes is difficult to express in a cathardic way without the use of a swear or two.
I’ve noticed a lot of former JW’s have become either Atheists or Agnostics. To be honest, I can’t see accept those beliefs either. Let’s say I had a son who was only a baby that died a six months, am I wrong to believe that I would see him or do I need to accept the cold reality that I never will? Because I hear Atheists say live your life to the full now and do what makes you happy but what about if we were talking about a baby or a young child that died, even a young adult who didn’t even began to live their life?
Yes, there are a lot of atheists and agnostics here. I believe there is a post somewhere with a Pew poll regarding religion that found that of the 2/3rds of born-in JWs that leave, roughly half become atheist/agnostic. This is somewhat understandable, if you consider what someone goes through upon leaving the JW religion. Upon finding that they've been systematically lied to (many for their entire lives) in the name of God can certainly cause someone to question the existance of any god. Also, the realization that you've been lied to for so long can often lead someone to resolve in their hearts not to accept anything without evidence. That is a road that often leads to atheism. If you stick and engage in some of the lively debate that goes on here, you may find some of your posts are debated by atheists. What you probably won't find, however, is someone here coercing you to become atheist by causing your family to shun you otherwise.
Regarding the homosexuality issue, if it were okay then why can’t two people of the same sex produce a child? And after reading a recent 2014 article (Not a JW or religious article) about gay sex, it states that gay sex has been leading to increasing sexual diseases even to those who use protection. It seems that most people on here are okay with gay marriage. Of course, it is also wrong for me to hear on news how some anti-gay extremists go to far and kill off or murder gay people. That is horrible and something that makes me sick to the stomach to hear gay people being murdered like that. However, I am the kind of person who wouldn’t condone the practice not just because of religious issues but the increasing related diseases that has been associated with gay sex.
Assuming homosexual practices cause all manner of ill concequences upon the practicer (this is debatable, but let's make the assumption for the sake of argument) what does that mean for you? I'm assuming you don't identify as homosexual, so who cares what gay people do? Upon waking up to the full scope of the lies that you once believed, you may find that you're unwilling to condem other people who aren't hurting anyone (except, perhaps, themselves) based on beliefs that might be wrong. What two consenting adults do in private is no business of mine, and it certainly has nothing to do with the moral charecter of those adults in any areas in which I might have dealings with them. Because of this, I find it impossible and morrally unconscionable to condem homosexuals.
Welcome to the forum, I hope you stick around. You sound like a thinking person that's out to find what the real truth is, and this site has certainly been a help to many in that regard. It's also a tremendous support to many (myself included) as it can feel like the floor is falling out from under you the more you learn.
