Religion?

Do we really need it?
I say no.
The cause and effect of religion leads to nothing but groups of different beliefs that have waged war on each other for not accepting their beliefs. Without religion their would be no blood shed by religious cults and will prevent mass war between other civilizations belifs.
Although without religion most people would have nothing to base their lives on and could possibly lead to mass anarchy if their are no rules to live by and belive there is no punishment to their life choices.
If I had to make the choice id take it out, even though im a religious person because I see the chance of less world problems/arguments without these beliefs.
