Keyword in your message is "may".
As to whether Vaxry was "really" promulgating hate... Refusing to acknowledge and respect a person's gender identity is transphobic.
Condoning this behavior (and victim-blaming the person who called it out) is transphobic.
When trans people and trans allies have positions of authority in an open-source community, public transphobes will get issued preemptive bans for the health of the community and the project. It is altogether fitting and proper that this be done.
Oh, and the fact that Vaxry slagged off Lyude publicly in his blog for good-faith enforcement of the code of conduct (as she has the authority and duty to do) just means that FreeDesktop would ban him again harder if they could.
It sounds like abuse of power
From what I see they both slagged each other.
Again though, I'm asking for where's the spreading of hate.
It'll be wild to look back on all this when the spell finally breaks. Do you remember that one time people lost their shit over pronouns?
Just to be clear.
