The dumbest fucking arguments you've ever heard.

[robvalue]

The dumbest argument I think I have heard has been on the forum a couple of times, and it is this:

"I choose to believe it."

As well as being intellectually bankrupt, it's also a contradiction in terms.

The second most stupid one, again I've seen it on these forums is:

"It's not impossible there is a god."

Of course, that's an unsupported assertion anyway, and how they turn that into belief powerful enough to build their life around a specific religion I'll never know.
