welcome, I'm an ex Muslim too 
if there is a god called Allah, why did he created us solely for the purpose of worshipping him? would it hurt him if we do otherwise? if it hurts then he's not an omnipotent god & therefore not worth worshipping.. another thing worth mentioning, in my opinion Muhammad may never existed at all either, if he did, he's certainly a madman, not a prophet..
as the apostasy law, we the atheists never physically hurt anyone in our conversion, why sentence us to death? Islam welcomes anyone who wishes to convert into it, but aggressively against those who leave it, and it call itself a compassionate religion? lol
