The "crusader" anti-UFO zealots are engaged in a debate, not in seeking the truth. In debate, you don't give the other side information favorable to its argument. You let them find it on their own.
I have also found that there is more than enough critical assessment of various UFO incidents by the researcher themselves. They are certainly more critical of their own field than the so-called skeptics are of theirs.
