I learned from following news about Hillary Clinton that no story is credible until reputable news sources pick it up, particularly if it is about someone the Right wants to smear.
If anyone needs a reminder about that, I tweeted to #ThankYouHillary thanking her for a letter from her I received after I'd been discharged from the hospital home to hospice (it's on hold right now, apparently I die as slowly as I write). From the tweet and letter, you get that I am terminal, that the letter inspires me and makes me happy. I got something like 1500 responses of some kind (likes, retweets, etc), and some of those are people trying to convince me that someone I admire, who gives me comfort as I backstroke toward the drain is really a terrible person who ran a pedophile ring and, well, you know. Some are bots, but others, they seem really desperate and personally invested in convincing me. So, yes, I reserve judgment and look for credible sources on pretty much everything.
Mr. Tyson has long been in the sights of the anti-intellectual Right for promoting science, curiosity, education, and fact-based understanding of climate change.
Which is not to say that this story is untrue. Plenty of men in the science and skepticism field have been predatory dicks.
But I will wait and see if anyone trustworthy backs up this story.
This is where I am. It would hurt if the allegations are true, but under the right circumstances, I would believe. When Johnny Depp was accused of domestic violence, I reserved judgment, but really hoped it wasn't true. Then at a certain point, believed. I went to high school with Johnny (though I remember him only as my friend's brother sitting on the couch or passing through the house), was good friends with his sister and only lost touch a few years after high school, when Johnny was becoming a star. I kept hearing from friends what a great guy he was, how charitable, how generous he was to his family. But I kept an open mind from the second I heard the allegations.
