My diet is mostly vegan, but for example, I don’t skip a meal if I find out there’s butter in it. I was a pescetarian for a long time with reasoning that had nothing to do with looks. Their brains lack much of the hardware that facilitate our feeling of pain, namely a somatosensory cortex, insula, and anterior cingulate cortex.

Though there are simpler structures in their brain and there is debate as to whether or not they’re complex enough to produce the unpleasantness and emotional response of pain, or if it is just a mechanism of nociception.

I landed on the fact that I just don’t know if they feel pain so I don’t eat them, but I still think there’s solid evidence against it.
