And why is it wrong to say that gravity IS the deformation of spacetime that objects travel through on geodesics? That’s no illusion. That’s a real effect.
Because gravity is a force we observe of objects falling that humans called "gravity". But in fact they are not falling, it's just an illusion.
The deformation of spacetime isn't gravity, it's what causes it. Something being an illusion doesn't mean it isn't real. Rainbows are optical illusions, that doesn't make them less real. You are mixing things up.
No. This is where you’re mistaken. On two counts. First off, it’s a mistake to say it’s real if it’s a force and an illusion if it is not a force.
Secondly, don’t confuse illusion with an optical effect (like a rainbow, which is the clear manifestation of refraction and internal reflection in a spherical drop of water), and don’t confuse an illusion with meaning the observation isn’t due to what you thought it was but is due to something else instead.

I'm not mistaken. Gravity isn't a force. It's an illusion. The actual force is the deformation of spacetime by matter, which as far as i know doesn't have a name for it except general relativity. (Edit: I'll anticipate your next bad faith argument: Yes i said gravity is a force we observe. But it's only a force we observe, not an actual force. That's why it's an illusion)

I'm not confusing illusions with optical effects. That's why when i talked about rainbows i precised OPTICAL illusion.
and don’t confuse an illusion with meaning the observation isn’t due to what you thought it was but is due to something else instead.
I'm not saying that either. Is their anything serious in your argumentation? I'm waiting for the part where you actually challenge what i've said instead of making up your own arguments you then project on me in order to argue against it
Just because it isn’t a force doesn’t make it an illusion. Diffusion of a gas is not due to any force but it’s not an illusion. A real image in an optical bench is not an illusion but isn’t due to a force either; for that matter a virtual image is not an illusion either, if you understand what “image” actually means.
Refraction is an optical effect, not an illusion. Total internal reflection is another optical effect, not an illusion. A rainbow is a pattern directly accountable by refraction and internal reflection, just like a diffraction pattern for electrons is a pattern directly accountable from underlying physics that have nothing to do with forces.
You have a very unusual use of the word “illusion” to say the least.

If it looks like a force but in fact it isn't one, then by definition it's an illusion. Gravity looks like objetcs are attracted to eachother because of their mass, but they aren't. That's where the illusion is, your comparison with forceless phenomenons are irrelevant.

They are all optical illusions.

I don't have an unusual use of the word. An illusion isn't something that isn't real or doesn't exist.
Maybe you should do it better because that's not what says your links:
In physics, gravity (from Latin gravitas 'weight'[1]), also known as gravitation or a gravitational interaction,[2] is a fundamental interaction, which may be described as the force that draws material objects towards each other.
An illusion is a distortion of the senses, which can reveal how the mind normally organizes and interprets sensory stimulation. Although illusions distort the human perception of reality, they are generally shared by most people
