True, but in this case, the economy of scale (for EV) are not there yet, so I don't know if it is a fair comparison. The tech is still changing and advancing.

But on thing is true, the E motor is more efficient than it's gas counter part in converting its energy into work.

Thanks - it’s something we’ll just have to keep our eye on, and to make sure irrational ideology doesn’t get in the way (on both sides).

True.

However, the entire system for gas engines is something like this: pump oil, transport, refine, transport to station, fill tank, burn fuel, work.

For the electrical car it's something like: pump or dig fuel, transport, burn fuel to produce electricity, transmit electricity, charge battery, run electrical motor, work.

The electrical system has more stages, each with its efficiency loss. The electrical system is still probably more efficient, but not nearly as much so as most people think. The relevant issue is how much of the fuel winds up producing work, not the efficiency of an electric motor, which uses electricity that has nalready been produced with its efficiency losses in the process.
