The problem with Orthodox Judaism is that it presents God as a freaken douschebag in ways that contradicts Tanach.
First of all, Orthodox Judaism has the concept of the nonforgiveness of sins whereas we previously learned that God freely forgives (Isaiah 55:7).
Secondly, Orthodox Judaism teaches that you have to follow all that bull shit and then God MIGHT give you what your needs are and you can fuck yourselves with what your wants are. The Book of Psalms would disagree. "Delight thyself also in the LORD; and he shall give thee the desires of thine heart" is Psalms 37:4.
