I think it's helpful, if it describes people who would prefer a full vegetarian diet, but understand that humans are omnivorous and need meat from time to time.
We don't though. You can be perfectly healthy without ever eating meat. The only vitamins that humans "need" to eat meat to get (basically vitamin B12, and sometimes D) are only present in factory farmed animals because they're supplemented in those animals' diets. Skip a step and just take those same supplements yourself.
How long exactly is "from time to time"? 'Cause it's been 36 years for me and I haven't felt the need for meat yet...
There are plenty of ways to express that you value vegetarianism without making false or misleading titles. Part-time vegetarian would be fine.
Yeah but people readily accept almond milk and rice milk, etc... and say, “language changes.” And vegetarian “sausages”.
Sure, but I would be pretty annoyed if someone sold me almond milk as "utilitarian milk".
Oh, and also many countries do not allow almond milk to be labeled as milk in any way.
