Did I read once if you have the polarity wrong on the coil it will cause points to burn also?

If coil polarity is reversed it will still spark but the spark is weaker and the ignition system isnt as efficient with more heat losses, and the coil has to work a bit more as the voltage has to ramp up slightly higher. It doesnt affect coil current or points life to any major extent, however.

So theres two of us with that problem lol lol

The DC LV Primary winding resistance (like 3 ohms) is the same regardless in which direction current flows through the coil....and the coil current is the current the points have to switch on and off and on and off,,,,,,,,,,
