Let this incident with Kainoa/Firefish and those alt-righters serve as a reminder that many of those nazis are determined to capture communities and projects because they cannot build one of any significant size or market on their own. Almost nobody wants to use or advertise on their cesspools of hate that they call social networks and Elon acquiring Twitter, however expensive for Elon (good), showed them what's possible by hitching themselves to something that many people find valuable and care for.
Let it also serve as a reminder that even plenty of us in the wider queer community are unable to quickly realize that we're dealing with an alt-right nyazi because many of us haven't been consistently subjected to their patterns of abuse and "befriending" they intentionally use with those that they know are not politically-aligned with them. I'm not attempting to excuse anything, but that seems a likely explanation. Hopefully now with this experience under their belt Kainoa/Firefish will be more cautious and try to background check thoroughly. The global alt-right movement is highly organized and coordinated and it's very unlikely that this was just a couple isolated dolts unconnected to the rest of them. Deception has become an important part of what they do and while many of them are terrible at it they often attempt it.
