In a similar way, letting a known something person speak means they're not intolerant of something. I mean, yeah, you could make that argument, but it sure doesn't seem substantial or useful. That's the point of Xyism at the end: it doesn't have much to do with functional programming , and functional programming is what the conference is explicitly about.

And there is an explicit threat against assholery: perform it and you'll be excluded. Don't and you'll have the same protection any other person has.

It is implicitly not about a very large range of things, namely mostly stuff that isn't functional programming.
