>I certainly don’t want to see sexist speakers at conferences, I don't want to see a sexist talk (as opposed to a-sexist talk), but an 'objectionable' speaker really shouldn't be a problem if their talk would otherwise have merit and they can be reasonably expected not to be objectionable on stage. No-platforming and economic warfare are tactics used by the worst kind of political actors, the kind you should be actively avoiding if you value your own livelihood, let alone anybody elses.
