One of the common arguments I often hear in support of OJ is that, without God and the Torah, there is no purpose to life. Through the Torah's commandments, God has given us purpose and a way to attain a place in Olam Haba, the World to Come.
I have two problems with this "reason" for going along with OJ:
1. If, as many OJ adherents claim, Olam Haba is sitting in the presence of God and enjoying the Torah with Him, then I am not really interested. They make it as if the reward is basically hearing a Torah shiur (class) from the Man himself. Sorry, but that just doesn't do it for me.
2. Ok, so the goal is to get to Olam Haba. Then what? Do we sit around God and hang out with other do gooders? What is the purpose of that? So Olam Haba really just gives you a goal for this world, but then the problem arises again since there is no purpose to Olam Haba itself.
Sure, if you are into OJ, then living OJ with the addition of a closer connection to God would sound great. But in itself, that is a lame carrot to dangle as a reason to be OJ.
