I wonder if there exists people who aggressively believe mushrooms are plants, similar to people who defend Pluto as a planet.

It was only in 1969 (nice) that fungi officially became its own separate kingdom.

I think an issue here is that taxonomic and colloquial definitions don't always agree.

Spiders are colloquially bugs, but they're not taxonomically "true bugs" (which is itself a colloquialism for Hemiptera). Tomatos are colloquially vegetables but taxonomically fruits...but afaik vegetable is a purely colloquial term anyway.

And as someone else in the thread mentioned, colloquial berries are not always taxonomic berries.

So...colloquially, "plants" sorta means, "macroscopic multicellular living non-animal thing," but taxonomically it's something else.

Similarly, “a planet” can be understood in technical or colloquial context which changes the meaning. It can have a specific meaning or a vague flexible meaning, just like with berries.

BTW raspberries are my favorite berries… sort of. Watermelons are pretty good too.

Actually planet doesn't have any hard set definition, we kind of just do it case by case because its damn near impossible to come up with a rigid definition that doesn't suddenly classify some planets as moons or some moons as planets or create weird situations in which an object can switch between the two.

The International Astronomical Union (IAU) defined in August 2006 that, in the Solar System, a planet is a celestial body that:

  1. is in orbit around the Sun,
  2. has sufficient mass to assume hydrostatic equilibrium (a nearly round shape), and
  3. has "cleared the neighbourhood" around its orbit.

https://en.wikipedia.org/wiki/IAU_definition_of_planet

And in that same article:

It has been argued that the definition is problematic because it depends on the location of the body: if a Mars-sized body were discovered in the inner Oort cloud, it would not have enough mass to clear out a neighbourhood that size and meet criterion 3. The requirement for hydrostatic equilibrium (criterion 2) is also universally treated loosely as simply a requirement for roundedness; Mercury is not actually in hydrostatic equilibrium, but is explicitly included by the IAU definition as a planet

That's not even addressing the issue of rogue planets which were ejected from their star system. Many estimates say they outnumber the stars. Obviously when a planet is ejected it doesn't just disintegrate but by that poor definition it's no longer a ""planet"", so it's clearly a problematic definition.

If you’re talking about tomatoes, the difference is the context, and it isn’t a choice between colloquial vs scientific taxonomy, but between culinary/nutritional vs botany/taxonomy (and). You can talk about either in a colloquial context or a formal context, though generally there isn’t much reason to talk about botany in a colloquial setting.

From a nutritional perspective, mushrooms are generally considered vegetables, too.

afaik vegetable is a purely colloquial term anyway.

I thought you were wrong but I looked it up and I appear to have been mistaken. It makes “tomatoes are fruits, not vegetables” sound nonsensical, as it implies that “vegetable” is a different taxonomical option, when really it’s just a word for objects with a particular collection of traits that are relevant in a different context. What we should he saying is “While tomatoes are not fruit in the food pyramid, taxonomically, they are.” Doesn’t really roll off the tongue, though. Maybe “Tomatoes are vegetables AND fruits!” would solve that?

but what about berry club? which things count as berries now?
