People like him do crazy, self destructive things like this because of limited choices or desperation. You claim to understand the larger context but you’re taking everyone here to task for bringing it up and also falsely claiming that others here are excusing the existence of this particular double decker RV (and of other aspects of squalor that no-one here excuses, either). That’s what your original post said.
Again:
I was discussing the members of your new community, who if they’re droning on about “personal responsibility” likely also subscribe to the two former arseholes and haven’t voted blue since 1968. You may be surprised how well you end up fitting in with them.
