I'll focus on Christianity:

Much less discrimination against women and gays

No more pro-life assholes

schools can focus on actual science rather than nonsense

people not wasting time praying.

Here is an old thread I made about why I hate religion.

Once I'm dead, I won't care any more, unless I come back as a zombie. Then I should be concentrating on getting rid of samurai swords.

Really, I guess the purpose is to provide a goal, to give me something to do until I die.

I am beginning to see a conspiracy with a few posters on here who are trying to zombify every post. That is just irrational. When the zombies come, we will deal with them, everything else is just speculation. Everyone knows that the evil, pink, invisible unicorn is the real threat. I rest my case.

As for question rightofcenter, the exact same question has been answered, and is currently being answered here. It would be nice if a mod could merge these superfluous posts.

Amazingly,it is in fact possible to debate without large amounts of profanity and vulgarity. Just a thought.

What's the point of breathing?

What's the point of staying alive?

We want to survive.That is probably the nost basic instinct. As a whole, we want to pass our genes on and ensure mankinds continued existence. Therefore we want to fight things that endanger that, or the welfare of our offspring.

If you really need a reason to justify helping humanity, I'm not sure what to say. Maybe we should just let people lob nukes around based on beliefs?

Irrational beliefs:

That if I drink this plain water, or eat this sugar pill because someone had it near some substance of dubious medical value, it will cure my disease.

That if I kill enough infidels and myself along with them, 72 virgins will serve me in heaven.

That if I pray over my sick child she won't require life saving medical care.

That demons exist. My children are misbehaving, thus they are infested with demons, god wants me to kill them.

That a collection of cells harvested from a dead fetus is in fact a human being, thus it is unethical to use them to save the lives of real human beings.

That God talks to me, we must invade [fill in the blank].

That Jesus is coming back soon, why worry about the environment?

That god hates fags.

That the basis of modern medicine, evolutionary theory, is obviously a ploy of the devil, thus we must teach our future generations of potential researchers that instead, god done did it.

Why must they be eliminated? Why must society be protected? Are you really this disengenuous, or are you trying to make some sort of back handed point?

Posts such as Why is Genocide wrong follow this similar line of reasoning, the heart of the posts deal with discerning what morality is? Is it fixed? Can it be changed? Are right and wrong merely concepts, or do they really exist?
