You know, I think you were bullied when you were a kid. Dont me get wrong we all had run ins with bullies. Some more than others. But I think you were bullied a hell of a lot.
Maybe it was because your size and your grades. That bullying had a sizeable impact on your life. Sarcasm and cynicism comes from your childhood. It could even had derived from a relative.
Im sorry that happened to you. Today there has been a little more focus on the problem of bullying. I can only hope you dont pass on those undesirable personality traits to your children and grandchildren.
It's not too late to change.
Typical Christian hypocrisy. Go read your Bible - I think you missed the second half of it or so.
Oh, and when you wonder why people are waking up and seeing why religion is bullshit - look at yourself. If God can't even "change the hearts" of assholes like you, how did he create everything?
