No, but these things are:

"Thank you, Duncan. I honestly think you’ve changed my life."

"Miss you. Virtually." (after being blocked)

"You're one of the best people I know." (contrast with the present-day "we don't know each other at all, wtf")

~"I'd gladly send you $200 if it meant you could get a babysitter and come to my drug/sex/music party."

And this:

(There are plenty more examples.)

It doesn't quite work to "remind" people of a thing that isn't true.

What he is being accused of are, basically, his literal actions, on-the-record.  One might object to summaries like "manic" and "crazy" if they seem inappropriate, but in this case they are clearly appropriate and given all of the evidence, the burden of demonstration is on "here's why this massive pile of obsession and harassment shouldn't be considered crazy."

(Or "here's why these hundreds of fevered and pressured messages that often contain paranoia and catastrophizing and grandiosity, including mentions of e.g. working 17 hours a day, 7 days a week and routinely sleeping less than six hours a night, shouldn't be considered mania, when that's almost literally the diagnostic criteria for mania.")

You're acting as if Caleb deserves normal baseline kindness and charity, but he burned his way through that months ago, and burned through the extra above-and-beyond kindness and charity of several additional people in recent weeks.  Nobody's setting out to be mean, but there's also no reason to bend over backwards to be nice (and the absence of bending over backwards isn't rude or bad or in any way decriable).

This whole comment section is Caleb reaping what nobody forced him to sow.

("I've been wearing my 'I fucking love science!' shirt since early college" doesn't make one a scientist.)

(Disambiguation: not the originally linked tweet thread, but the inciting incident that caused the originally linked tweet thread to be written.)

Standard M.O. from segfault is to simply never address this inconvenient bit of reality.  I would be slightly surprised if he replies at all, as opposed to ignoring this subthread now that you've posted the screenshot.

Are you seriously pretending that you don't know how to look at a tweet in an incognito window?  You seem to have been expertly doing so in, uh, "other cases".
