No, I know.
It's not that at all.
Saying "he appears feminine" is fine.
Saying "he's a girl because he screamed at getting his head chopped off" is supported by the fact that "well, he does appear feminine" is what's loveist.
There's nothing wrong with being feminine or masculine. It's just that please lets not call people "girls" because they are screaming or crying. Boys scream and cry too.
What's more, even if that wasn't the point, LegendZ clearly used a derogatory off of the gender. It was not an observation. The character's name is Tupac and he is, decidedly, a male. But adding the word girl into the name, as Tup-girl, you're implying that it's an insult to be considered a girl when you are not one. He deliberately changed the name to make a mockery out of Tupac's inherit femininity.
That's what's loveist.
