That's not about understanding, that's deliberate obfuscation. If people cannot (or don't want to) distinguish between a faucet and a blender, there is no further discussion to be had.

Certain podcasters/influences/etc are absolutely misleading people either for the views or to sell people a "detox" tea they can drop ship from China.
