Misgendered by Whom?

Neil deGrasse Tyson is determining Rudolf's gender based on Rudolf's anatomical features.

Santa doesn't know Zoology:

Both male & female Reindeer grow antlers. But all male Reindeer lose their antlers in the late fall, well-before Christmas.

So Santa's reindeer, which all sport antlers, are therefore all female, which means Rudolf has been misgendered. pic.twitter.com/fkHqhJM7dY

1. I appreciate that a scientist takes the view that Rudolf's gender can be determined by Rudolf's anatomical features. But from what I understand not everyone agrees with that ….
2. I'd listen more to whether Santa knows Zoology if the physicists knew more about reindeer flight.
3. As a correspondent of mine noted, the Rudolph story is thus "actually about female bullying (mean girls)." Perhaps the female of the species is more deadly than the male.
