I am talking about a passive load (like a resistor). Increasing the voltage will push more current through it.

No, the resistor will pull more current.

If you supply a 100 ohm resistor with a 12V100Amp power source, the circuit is going to pull 0.12 amps from the supply.

If you supply a 100 ohm resistor with a 24V100Amp power source, the circuit is going to pull 0.24 amps from the supply.

The supply isn't pushing current, the characteristics of the circuit has changed and it's pulling more current.

It's just semantics at this point. You say pull I say push. A 24V supply can push twice as much current (through a resistor) as the 12V supply.
