not sure why you put emphasis on "direct evidence". obviously nobody is denying that some people claim to have direct evidence of UFOs. or more precisely, direct evidence of UFOs not only existing (nobody denies that unidentified flying objects exist), but they themselves being evidence of extraterrestrials visiting earth.

i feel like you are significantly misrepresenting the argument made in the blog post and as a result are misinterpreting my critique. again, nobody is denying that some evidence that supports UFOs exists (in the sense of them being aliens). nobody is saying that subjectivity plays no role whatsoever when determining something as fact or not.

the blog concludes with "Seeking truth is great — but mingling truth-seeking with ambitions about consensus is one twitch away from the belief that “forcing my truth upon others is a good thing”". lets look at the context (which the author seems to value so much) in which this statement is uttered: fact checking trump tweets (which the author seems to deem highly problematic) and extraterrestrial aliens visiting earth (which the author seems to say is as reasonable to belief as the opposite). if you do not see the issue here, i don't know what to say.
