"1. Most atheists are full of themselves and arrogant."
Sounds like many of the Christians I come across.
"You see it in these boards, you see it in that sign they put up in Washington disrespecting Jesus and his birthday."
Your buddy Jesus wasn't born on December 25th. He wasn't even born in December if he existed at all, if your Wholly Babble is to be believed. How about you actually crack that book open once in a while and do a bit of research into your own religion before you go telling others how full of themselves and arrogant they are?
"2. Most atheists are apathetic in life. All they do is be spiteful and bitter towards others for no reason. They are very angry."
Yep. Angry that you goofy bastards want to replace our legal system with your holy book. Angry that you want to forcibly convert everyone to your cult and kill or deport anyone who wont go along with it. Angry that you demand real special treatment while denying basic civil rights to others while falsely claiming they're demanding special privileges.
"Why? They haven't found God yet."
I'm not going to play a cosmic game of hide and seek with your deity. He's omnipotent; I'm not. If he want's me to "find" him then he can show the fuck up right here, right now.
"3. Everything in this world has been constructed in such a perfect way."
You're either lying or incredibly stupid. I'm not sure which.
"There must of been a power behind the scenes creating the masterpiece that we see today."
In all honesty I fail to see how anyone with any small bit of knowledge about the universe and its workings can say any of it had to be "created" by anything but natural forces.
"The Big bang is a useless theory that has already been disproven by scholarly and respected theologians."
Theologians aren't scientists. I'd barely call them philosophers. They're in no position to validate scientific methodology or the fruits of such pursuits.
