Proponents of green energy and electrification of various domestic items are perfectly willing to support externalising various costs onto others, just to give one example.
Edit: Allow a lithium mine, or a rare earth processing plant, or an electrical waste site, in your back yard, and be happy that it provides employment for those around you, and then we can talk.
Also when did liberal and free-thinking mean someone was supposed to be in support of allowing costs to be externalized on to others?
