Because much complex falsification was required of Intelligent Design. The double standards are clear.
So let me understand your reasoning:
It is not okay to use telescopes to study the universe, you need other unspecified instruments, because people were, in your opinion, unfair to intelligent design.
Can you explain to me why telescopes are inadequate in cosmology, without reference to how unfairly some other subject was treated.
Your reasoning would be equivalent to telling a plumber that he doesn't know what he is doing because somebody was mean to the electrician.
