On the sickness of our community

You mean Lennart never stopped correcting him.

Correction is what happens to people when they come horribly underprepared for their talk, full of misguidance how things actually work or why those things exist there in the software to begin with, while defending their world view ( in Datenwolf's case in his world people with disabilities did not exists ) how that software is supposed to be written.

You do realize those talks more often than not are being record and that record later get's shared with the world right?

So you know that it's better to correct them then and there rather than after their talk because if you dont those correction would never make it to the recording.
