Nah it’s because some people have the arrogance to think they can impose some arbitrary self-granted authority over others who then have to listen.

It’s the same thing with vegans who think everyone else should be vegan. Or Christians who think everyone must follow their worldview. It’s tongue-in-cheek saying “fuck you for being different” and I think we’re all tired of that mentality from everyone at this point.

They are mad because they aren't educated enough to understand why it is true, much less that it is true. They will cling to their outdated beliefs and refuse to make a change that benefits others. I find much less objection to eating something like a cricket compared to an intelligent animal that is as smart (or smarter) than your precious golden retriever.
