Giving Leftists every possible keystone position of power to subvert, infiltrate, and kill you with is exactly how you get yourself into a mass grave.

The left can't build anything because all they do is seize power and squander it until they've killed everyone. Trying to feed into that by giving them ground to make mass graves, and then giving them an avenue of attack into your own system is not a solution, it's a guaranteed loss.

If you give a Leftist a keystone position of power, they will wear a skinsuit to get into that position of power and use it against you.
