Man thinks my atheism is due to tragedy

I received this email just a few days ago from a guy named Andy, and I thought you guys would get a kick out of it:

Hello Jake I know you must get some real harsh mail concerning your fate when you die and as a follow of Christ I want to apologize for that, I want to applaud you in your decision making for at least you have given it some thought and have come to conclusion, but what I do not understand is this, why do you spend so much time talking about a God you do not believe in, if I were you and did not believe there was a God there is so much more to do than waste my time on something that does not have any meaning. But the problem is Jake you have had your encounter with the I AM and have feel that He has let you down over the death of a love one and instead of trying to find the answer why you have chosen to go to war with him, spend some serious time again Jake just listen again to what he has to say, you may be surprised at the outcome. Well I do want to send you blessings to you and your family in the name of Christ.

This is why you should never just “trust” every dumb feeling that you have Andy; I haven’t lost any loved ones, and my atheism has really nothing to do with any feelings of bitterness towards your anthropomorphic God. Perhaps you fail to understand when I make fun of “Him”, I’m not actually acknowledging the fact a God exists. If I spent my time trying to disprove the existence of demonic space Unicorns, would you also accuse me of believing in the very thing I seek to expose as mere fantasy? As for your statement I should stop wasting my time since “He” doesn’t exist, I seriously wish it were that easy, but even your barely comprehensible email is proof religion facilitates ignorance. Do you have any serious proof a 2000 year old Jew was the creator of the Universe outside your barbaric and outdated book of Bronze Age mythology?
