If you can't agree with the fundamental teachings - the 144,000 and the Memorial™ are fundamental teachings - then I would suggest examining what it is that you agree with, and why.
If you are male, does the Headship Principle™ appeal to you? The one that puts females in a lower station, and requires submission to the husband or father? If you are female, does that same Headship Principle™ appeal to you for its requiring less of you, allowing you to cop out and let someone else make all the tough decisions for you?
Does the extremely structured lifestyle appeal to you, which leaves little room for socializing with family and friends who are not JW?
Do the rules appeal to you, that absolve you of responsibility for making your own decisions and at the same time surrender your decision-making to a body of individuals that you will never meet, and who may or may not have your (or your family's) best interests at heart?
Do you agree with the idea that in a medical emergency, you will be required to refuse blood transfusions for yourself, and on behalf of your spouse and/or children?
If there are teachings that you disagree with, can you, in good conscience, go Door-to-Door™ and attempt to recruit other people into the JW belief system?
Can you live with the possibility of having to shun individuals who leave the belief system - not for doing anything wrong - but because they disagree with certain doctrines and practices?
Can you, in good conscience, invite people to join the JW belief system, knowing that it shelters pedophiles and domestic abusers from justice, and attempts to silence victims of these individuals?
Ask yourself those questions before you commit. If you can still join the JW belief system after seriously considering those questions, then you deserve each other.
