It was a stupid reaction.
Buckley had every right to make that little comic, the amount of backlash for that was completely disproportional even if he had made a terrible comic about killing Skyrim children or something.
A “bad tonal ahift” is nowhere near bad enough to warrant this kind of hate.
He absolutely did have every right to make that comic. And his audience had every right to respond “Whahahahahahat the fuck was that?”
That was the intended audience for the comic at the time, though.
CAD was very much immature nerd humour (as was the style at the time), and it’d be inevitable that a sudden tonal whiplash to a serious tragedy around a miscarriage, out of seeming nowhere, would be received poorly.
