Why a Morality Based in Theism is Weaker
I thought I'd make a spin off of this thread's opposite, just for a little fun. Only in this case, I'm not going to set it up as a game, I'm just going to explain why.
Theists have often espoused the idea that morality comes from god, which is obviously not true, because there are many different moral codes out there and only one of them can be right. So, even if one of them did come from god, the rest of them had to come from somewhere else - so even if we assume any morality came from god, not all morality did.
And certainly atheist morality didn't. When atheists come up with their moral code, we have to think about why we believe certain things are good and certain things are bad. We have to consider what we think will have a negative impact on society, and what will not have a negative impact on society. This gives us a clear understanding not only of what we believe to be good and bad, but also why.
Theists do not have that strong backbone in their morality because they follow a moral code given to them, and tend not to question it. For example, I've never known an atheist who has believed that homosexuality is immoral - because they all considered the topic and found it has no negative effect. Christians, however, believe that homosexuality is immoral because it is described as an abomination in the bible. In all of my time debating with Christians, not one of them has given me a single reason why I should believe that homosexuality is immoral other than "god said so".
Another reason why theistic morality is weaker is because theists believe that the inevitable judgement of their actions will come from god, after they die. But god has no real, visible effect on their lives - he takes no interest, and leave them to their own designs. Because of this, theists seem to have less qualms about breaking their own rules, because they know that there will be no real, immediate consequences.
Thanks for reading.
