They need to declare Earth a leftist-free zone, and use Ateroids to wipe them out.
But, but, but, that would make earth a magnet for assault asteroids. Why don’t we just do background checks on the asteroids. Of course the enviro-wack jobs would love nothing more than to have a couple of football field size asteroid strikes to wipe out humans (with them excepted of course) and return mother earth to a place where pink unicorns frolic under rainbow skies. And it is always 72 degrees and the humidity is just enough to be comfortable. Idiots. REAL radical left wing extremist demokkkrats scumbag enviros would do the honorable thing and remove themselves from the equation for the betterment of the world. But, they won’t. (sigh)
Not a very good analogy for the futility of gun free zones.
If you declare Earth to be an asteroid free zone it will not encourage asteroids to target Earth like declaring schools to be gun free zones encourages psychos to target schools for shooting rampages. Asteroids don’t care if their victims can shoot back.
...will they consider the war on poverty through the same lens?
No, they won't - but that doesn't make it reasonable or acceptable for conservatives to be their equally hypocritical mirror images.
