Wow. You really are a stupid, sad, and miserable piece of ****, aren't you?
Nah, you must be faking it.

For example, your nonsensical response that creationists say that they are
too stupid to understand creationism, so it must be true, just proves the
point (if you actually tried to think about what you say before you say it
then you might avoid demonstrating just how idiotic you are). Do you also
believe that they claim that evolution must be false because they understand
it? You would be so much more interesting and entertaining if your
"arguments" weren't so mindless.
