Welcome Atheist-R-Stupid, it is great to have another Watchtower apologist on board to spice things up. It shows the casual observer the mindset of a JW, which in your case seems to be a huge amount of pent up agression, and black and white thinking.
If all JWs left, they wouldn't all support abortion, etc, as you state, then you are just parroting the thinking the Watchtower wants you to believe.
Furthermore, some of the things you have mentioned may be commendable aspects of the JW community, but that does not make the religion healthy, once considering all the evil aspects of it. As Watchtower likes to say, you wouldn't drink a glass of water if you knew it had poison in it, regardless of how clean the rest of the water was.
