My point being: 'give up' is what some people, who would otherwise be our allies, are hearing. Stop telling *them* to give up.

The actual point being that nobody who hears "give up" when they're told to stop wasting energy on the "solutions" provided by the people who don't want the problem solved will ever be an ally until they first stop giving oxygen to the non-solutions. Until then they are an adversary, not an ally.
