I know why Atheist get frustrated but why do theist...?

We don't hate atheists; we just want equal time in public forums without censure to present what we have observed and learned about origin science. The idea of a truly open forum, especially in higher ed, is a joke. There are scientific papers and treatises from respected researchers that support ID but they are never allowed space in leading science journals. There is much bias and censorship in this area (if you watch the doentary Expelled, you will see examples of this).
