Rosh Hashanah marks my second year of rejecting Judaism. So this is a special day for me. It is also interesting that I gave up Judaism during Rosh Hashanah, a time of the year where people are supposed to feel closer to Judaism. I still remember what I did during Rosh Hashanah. I was reading Thomas Paine's "Age of Reason" still when I was a believer. But I was already a really bad believer, I needed further reassurance from someone, I decided to read Paine. In the middle of reading Paine I finally concluded, after long time spend on skepticism, many many months, that the fundamentals to Judaism are vile and repulsive. So I took a Chumash in my hands and expressed my heresy, "this book is wrong, what it teaches is wrong, it is falsehood, and it is also evil". Something to this effect. That was it. I finally gave up Judaism. I was a little scared to do that, but I did, two years ago.
By the time Yom Kippur came about I was already a non-believer. But I went to shul on Yom Kipper (actually I was at shul on this Rosh Hashanah too, but I did not daven, of course). I still davened on Yom Kippur though it was really hard for me. Each time I read a verse I kepted on thinking why I disagree with it and why it is non-sense. I also realized the entire scene in shul is kinda stupid. People dressed funny and praying to imaginary beings, so it was hard for me to sit through all of that. But I was not able to stay for the whole service. The bowing down part was too much for me. I had to leave, I could not possibly bow down. Jewish people say that no one can ever bow down to a false god, that is idolatry, and I agree, since there are no gods it means we can never bow down to any. I was not able to be at shul for that. I got up and left.
Jewish people have a really tough time understanding that it is hard for secular Jews to "just say the words and sit in shul". No, it is not so simple. It is hard to say those words and hard to be at shul if you do not believe in those words. It is understandable that a non-religious Jew who is interested in being a religious Jew can "just say the words", because they do not bother him. But if you are a secular Jew those words really bother you, and it is hard to say them.
