Welcome JWINQUESTION:
I'm 27 and finished college at 23 but miss it and wouldn't mind going back for degrees in things that actually interest me. You are never too old! More than half of my graduating class were over age 30. Anyway, some background, I was a JW from 3rd grade unitl age 24 when I stopped attending after New Light about the "generation." The reasoning they had for New Light didn't make logical sense to me. I had already been questioning the logic surrounding the non-acceptance of blood transfusions. I decided exactly like you that if it's the Truth, then it can withstand ANY scrutiny! I took a year off to research specific JW doctrine and what I concluded about blood, 1914, 1975, etc convinced me not to waste any more precious time with the organization.
Keep asking questions and seeking answers! Belief sytems play a large role in your psyche and subsequently your actions and decisions for the rest of your life. If you have never truly scrutinized your belief systems and have only blindly gone with the wind with them, then you might live the rest of your life fully formed by an organization you don't want to bother questioning. Never stop seeking knowledge. In fact I advise you to take a Technical Communications course in college and pay attention to Logical Fallacies. You will be able to critically analyze each paragraph in a Watchtower mag and see how often they commit these fallacies!
Also as a side note regarding homosexuality: Homosexuality has been observed in the animal kingdom across hundreds of different species and even in long-term homosexual bonds between two mammals that lasts their entire life-time! It is a byproduct of creation/evolution/natural selection/whatever you want to call it. How could a God condemn the actions of the animals/humans he created when he instills these behaviors? Also combine the points made previously about STD's between straight people, and the points about pro-creation not being of any concern or necessity in even married JW couples.
Cheers
