Anti-gen is the new Religion and anyone who has one is evil. :)
We got ours in the first place to run the air conditioner in case the dogs got over-heated, which they will if they are keen and it is too hot while they are 'working' during their events. They don't stop and will die trying. You can toss them in a pool of water to save their lives but having air conditioning is also a good thing.
So in between dog events where sometimes we have to park on asphalt at over 90F (Abbotsford eg) it turns out where we just RV camp there is no need for air conditioning but we do have the Honda 3000. So we use it. So that must mean we are evil, non-green, and should be banned from all RVing! We must have it because we can't survive without it, being such sissy city-dudes. :)
Sorry about that! Which all goes to say it is not about morality, it is about the technical aspects of getting by off-grid.
