Yep. Ridicule, lies, and intellectual dishonesty (like strawman arguments).
So-called debunkers say things like, "People see fuzzy lights in the sky and stupidly assume they're extraterrestrials." "They're just fools."
Or, "People who claim to have seen UFOs are all liberals and retards."
"DEI distraction."
"Squirrel!"
Best to just ignore the wags and blatteroons.
