I matters because religion makes it near impossible to have a universal set of right and wrong, and that the debate itself causes wars and strife for billions of people.
Surely not. I think I have given several examples above where the ideals that Jesus teaches are ideals that are consistent with, for example, the Secular Humanist manifesto I linked to. I know you reject both the divinity (possibly the existence) of Jesus, and you reject Secular Humanism. But it is clear that the two philosophies, at their hearts, are not inconsistent with each other, even though they come from completely different starting points.
So how can it be that religion (in this case, Christianity, with which I am most familiar) can be claimed to be at odds with a 21st century definition of morality?
At the end of the day, most religious people can not agree to a set of rights and wrongs because of their God. They simply cannot distinguish between a universal right and wrong, and the rights and wrongs set forth in their holy texts. And they will always fight to change the rights and wrongs to fit their God or Gods will, because in their mind, it's better for all people to believe and adhere to their religion.
You keep using this phrase ``most religious people'', and I don't know why. There is surely a vocal minority of conservative evangelicals in America. There is also a vocal minority of people who advocate all kinds of crazy things---if you believe in animal rights, would you like to be associated with domestic terrorists like the Animal Liberation Front? If you believe in environmental activism, would you like to be lumped together with people who firebomb SUVs? I would not like to be associated with people like Pat Robertson---simply because I happen to believe in the same God that he does---any more than SAM would like to be associated with Osama bin Laden.
Aside from this, you're still wrong about ``universal right and wrongs''. When it comes to Christianity, broadly defined the ``rights'' and ``wrongs'' are very clear. The point that I have been trying (very unsuccessfully) to make is that these rights and wrong are in no way inconsistent with what you would define as rights and wrongs. One of the two core commandments of Christianity is this: love your neighbor as yourself.*
Their intent isn't malice, but if they can convert the non-believers they are "saving" them from their own destruction, and it's their job as a believer to save as many people as they can. It comforts and elevates them, so everyone should be involved.
I will point out, again, that you are talking about a very specific flavor of Christianity.
We will perish for our non-belief no matter how right or wrong we were. Right?
If you say so This is certainly not what I believe.
