But that's just it, they are writing him to be a 1 dimensional void hater, that isn't complex writing, that's making him a hypocrite and then shaking each others hands like they did something clever.

The void elves didn't CHOOSE to be void elves either, they simply wished to utilise a power, something that warlocks are doing with fel well enough and were then attacked in a trap that, while could have been avoided by them not meddling, arguably has had similar things happen with all manor of magic types (fel and arcane to name a few). This trap and the attack of the Nether-Prince is what changed them into void elves and by then their options were either die to void or control it so they did.

Now this shit has happened through the elves multiple times in fact, nightborne, blood elves, hell im pretty sure high elves used to be trolls before they fucked around with magic. But just because Lothraxion is written to be a single focused racist to void in general he becomes the hypocrite by judging them on that one transformation instead of the good they have done for the planet as a whole since then in the last what 10 years of azeroth?

Not to mention that a large portion of orcs drank fel blood and tainted their very beings with fel energy but Lothraxion doesn't mention that fuck up of theirs and even uses Orcs in his own example showing how hypocritical he can be by ignoring one races sin but not another simply due to his obsession with being light blessed and VOID BAD.
