The harms and atrocities that come from dairy and eggs are arguably worse than meat itself

Certifiably cap, just from the scale of it all. Meat production has a non insignificant amount of environmental impact.

Dairy does too, but meat, you need more animals to kill.

and the former industries drive the latter to some extent

This is exactly backwards

Vegetarianism is neither ideologically or functionally different than any other form of animal commodification.

This is so absurd on its face that I don't think you're reasonable enough to bother arguing with, and don't think anyone reading this will think you are, so I'd just be wasting my time.
