For starters one worldview is no more "practical" than the other in terms of what each person accepts as true. You also can't really label Theism a "false hope" unless you know for a fact a Creator does not exist and I see no reason to have such surety in that.
Your stand is backed up by a book written by peasants and strung together with faith. My stance is supported by leading scientists and millions of years of evolution. I recommend you read some of Richard Dawkins books, they really do enlighten you. I do not know that the creator does not exist, but I know enough not to be fooled. Take the garden fairies for example. What if I told you that there are faires in your garden which you cannot detect with any of your senses? What if I gave no evidence? What if I told you that it is real and that you have to "have faith" in order for it to work. True, I do not know with 100% conviction that the fairies do not exist, but I am pretty damn certain. I do not believe in God as certainly as I do not believe in garden fairies.
Why do you get to be the arbiter of truth just because you're an atheist lol?
Because I have something called facts. I have scientists. I have proof and as I said, I have millions of years worth of evolutionary science on my side. You have a book which is written by peasents and endorses slavery. I am not the arbiter of truth, I am simply a moth who is drawn to truth. I simply stand with truth.
This is where you lose any form of good conversation and often the path atheists love to delude themselves with, as if they are the higher species who are not in any way blinded to the truth lol. Let me remind you, your personal worldview is not superior, it's simply your personal choice of what you believe exists.
"Athiest love to delude themselves". Funny coming from a religious lad from you, considering your life revolves around a musty old fictional book. I am a higher than you. My personal view is superior, because it can be backed up with facts. My views are supportable. My views can be proven. My views are testafiable. My views are logical. My views have withstood intense questioning. And yet they stand.
Yet your stands, well, it is all faith. Blind belief. It really is pitiful how gulliable one can be.
The question is not "are you happy" (at least from my point of view). The question rather is are you reaching the full potential of what you truly are and the implications of that, have you accepted an error about reality..... You can be happy atheist or theist because beliefs will never make you happy, the truth can make you feel satisfied but you may not even know what truth is when you see or hear it. You believing atheism is truth may give you a sense of pride because you think it is true but you could be dead wrong. In this sense objective truth simply evades you. Just because you're an atheist doesn't mean you stand for truth.
One of RationalMadmans questions was how an athiest can be happy knowing that they are just a organism on a spinning ball in a void of nothing. That was my answer. As to you question of happiness between athiest and religious folks, I still stand by my statement.
I am happy that I can face the world without needing to be wrapped in cotton. I am happy I can face the truth. I am happy that I don't need God to look over me in order to feel secure.
I believe that (to a certain extent), but have you considered what it means to be created by a Creator?
Sure, spending early mornings in churches praying to what you believe loves you can be a great comforter. People want to be loved. People want to be cared about. People want to be noticed. But I do not want love from a fictional character. I am proud that I am strong enough to love myself without needing assistance from God.
The universe is run by the laws of cause and effect (Karma) and beliefs are irrelevant to cause and effect. What's relevant to cause and effect are the things you actually do.
Karma is not real. When I say this, I mean the kind of karma which takes note of your evil and bites you back. Karma is just a label people put on unlucky events. Take this as an example. I hit a schoolmate in class and then fell over at lunch, breaking my leg. Karma did not snap my leg. Karma did not direct me to fall. I fell because of my own physical carelessness.
If you need help escaping the arms of religion, I recommend you read the book God Delusion. It uses logic, facts and reasoning to convince one that God is not real.
