My point is that selfishness and altruism exist on a continuum.
Agreed.
Sure, giving out of compassion will make you feel good, but it's less selfish than giving because someone promised you a reward. In the former you actually care about the well-being of others, whereas in the latter the well-being of others, if you care about it at all, is secondary.
Ah. Well personally, I've often performed charitable acts of one form or another (can be money some other form of assistance) without really giving a shit about the person in question. Not really. It's a sort of "throw it out there because it might do some good" sort of thing, but if it doesn't that's cool too. I'm not going to lose any sleep over it. I'll probably never know anyway, in a lot of cases.
I get what you're saying, but I disagree. Religion is unethical. It takes compassion and the human connection out of the equation. People don't kill because they fear God's punishment, people give to charity because they seek God's reward. It's as if people are sociopaths without being ordered around.
I think you're taking a very narrow view of religious people here. What you're saying does apply to some of them, sure. I'd dispute that it applies to all, and I'm not sure if it even applies to most.
You can't assume that just because a religious person sees it as their duty to give charity, that means that compassion and human connection have been taken out of the equation. A lot of the time they'll see giving as being genuinely the right thing to do, even if they do see their deity's wishes as being an added incentive for them to do the right thing.
You may be thinking more of Muslims you've known, whereas I've had a fair bit to do with Anglicans and various other sorts. With the latter, there are no specified amounts that you have to give and no specific threats if you don't give amounts which nobody has specified anyway. Their God wont send you to Hell if you don't give charity. He might be slightly disgruntled about it, but that's about all.
And that's exactly where nihilism comes from. Nihilism is a reaction to religion; it accepts the assertion by religious people and their apologists that without religion people would have no meaning and no morality. We need to transcend religion completely and affirm life. Not only because we value the truth, but more importantly because it's the ethical thing to do. Religion turns people into sociopaths who value nothing but themselves.
Does it? How would you explain religious people who are not sociopaths and do not only value themselves?
