Here's the line you speak of:
"ID is a fixed belief impervious to any conceivable evidence to the contrary."
So where did I say ID is "still a belief, just like evolution"?
I have to disagree with the 2+2=4 though.
So you don't believe that 2+2=4? You don't think ANYONE believes that 2+2=4?
how would anyone know that a belief corresponds to the truth?
If you don't care about truth, then don't sweat it. For those who do care about truth, how one arrives at and defends one's beliefs is important. Some beliefs are reasonable, some are not.
You didn't, I did. You said it is a fixed belief. You said 2+2=4 is a belief, and some stuff about 2+2=5. Of course I believe 2+2=4, I don't think it is a belief, I think it is a fact.
Your last paragraph did not answer how anyone would know that a belief corresponds to the truth. As you say, some beliefs are reasonable, some are not, but that does not make that belief a truth.
