Many things are possible interpretations in Revelation, but I'm not thinking you hit your target.
> white horse (peace)
"White" is generally thought to represent conquest, and with good reason, the primary of which is that the text says it's about conquest (Rev. 6.4).
- "White" = victory in war. The horses of the Roman generals in their triumphs were white. So also the white horses of the Persian kings: victory in war.
- In the OT, the horse is often a symbol of war, not peace (Job 39.25; Ps. 76.6; Prov. 21.31; Ezk. 26.10).
> he carries a bow ( no arrows)
The bow was an image of war and conquest. It doesn't need arrows to symbolize that.
- The only mounted archers of antiquity were the Parthians, vicious and brutal warriors whom the Romans feared. Parthians' skill as archers was common knowledge.
- The Persian armies, whose heirs the Parthians were, always included sacred white horses.
- Scripture speaks of the bow of YHWH as an instrument of judgment (war and conquest): Ps. 7.11-13; Lam. 2.4; 3.12 [as a victim of the Lord's wrath]; Hab. 3.8-9).
> he was given a crown ( as a king)
Yep. A symbol of power and authority, and the subsequent victory from conquest.
> he went out to conquer ( to give orders)
To give orders? No, to conquer (Greek νικῶν: To conquer; ultimate victory). Conquest is his purpose and goal.
> It has been used to sidestep all constitutions worldwide and give mandates. It has conquered the world without firing a shot. A bow without arrows. In peace the white horse has conquered the world.
Um, I don't think so. The stats (and I don't believe the figures: some are grossly inflated and others tragically underreported) say 1.3 million have died globally. Not exactly "conquering the world" kind of stuff. And I don't think the symbolism supports your interpretation, as I've shown.
> rides a red horse (blood, conflict, communism)
Communism? No. The word in the text is "fiery" (πυρρός). It's another symbol of war and bloodshed (blood, conflict—yes). Communism? No.
> takes peace from earth (deceives the peace promised by lockdowns, stimulus, masks)
This one is WIDE open. How many "fiery horses" through the ages have stolen peace from countries, cities, and towns, and turned people against each other.
> people kill one another (civil war, gov wars)
I'm not aware of many civil wars going on right now (just a few), and certainly not due to Covid. The Greek term indicates violent civil strife ending in death. I'm not seeing that.
> great sword ( weapons, punitive laws)
- The sword was often a symbol of judgment by war in the OT.
- It implies that the war this rider waged was fierce, devastating, and widespread, perhaps even global. This fits Corona.
- This Greek word (μάχαιρα) is symbolic of violent death (Rom. 8.35), brutal war (Gn. 31.26), and the power of governmental authorities to punish evil-doers (Rom. 13.4). It often speaks of violent human catastrophes (Ezk. 21, especially vv. 9-10).
I'm finding I don't agree with you, but glad to talk about it more.
