Is religion really poison?

I know, I keep chanting it to myself: “Religion is poison, religion is poison...” and there is much more to it than just the rhyme.

I really think it's a potent poison for the following reasons:

• It's totally irrational, and frankly, in the 21st century, we should all know better 
• It's promising goods it can't deliver on, like eternal life 
• It's a form of constant pressure on people, through guilt and other forms of manipulation 
• It's mental abuse on kids that are brainwashed when they are too young to know better 
• It's sometimes physical abuse on many other kids 
• It's a baby-mill, forcing women to have too many kids, regardless of the planet overpopulation 
• Finally, it screws up your Friday, or your Saturday or your Sunday!
