It's being resisted (weakly) by atmospheric pressure. It's a push on push effect, always.
This sentence is meaningless, as usual from you. No word in it refers to something clear, well defined, measurable.
Anyway, i repeat: atmospheric pressure, and water pressure as well, exert a push
from bottom to up on every material body immersed in it (water or air). No brainwashing, no shoehorned science, no conspiracy, no hard mathematics, only the old
Archimedes principle:

https://tinyurl.com/nhv99ncit's the same principle! Understand? A push bottom-up, not the other way around! No way to argue this, sorry for you. The only way to negate this is to stick your fingers in your ears and sing LA LA LA! Do you want stop saying bullshit at last and open your eyes? Saying air pressure is responsible to push down objects is outrageous! Okay, i repeat,
no brainwashing, no shoehorned science, no conspiracy, no hard mathematics, this is a first grade level experience that everyone on earth can prove beyond all doubt, it was discovered more than 2.000 years ago, and nobody ever did refute it. Oh my god, this guy is driving me mad.
In a post of few minutes ago you say:
The simplest way to use it is to think of weight as a measurement of mass. If you have a brick you are holding mass. If you want to know what the mass in weight, you measure it by putting it on scales. Simple!
Speaking about mass and weight is speaking about gravity! The weight is the force that pushes a body towards the centre of the earth. The air pushes it bottom-up!
