You Do Know He's Called the Brennan-Monster, Right?

I just had to point out, I was looking for criticism of David Brin (for being a vapid ideologue), and along the way I found a thread of people talking about SF and politics generally. A bunch of them were saying Niven was racist and evil (for having an objection to the welfare state and illegal immigration), a pretty leftish group, but what was hilarious was, they couldn't say enough nice things about the Protectors. E.g.:

Don't forget that Jack Brennan, the human Protector, a superintelligent creature genetically compelled to care for his fellow humans, spends his time and money agitating for rehabilitation of criminals rather than (say) going round beating them up like a normal superhero would.

This is what is known, to tropers, as MisaimedFandom. Brennan also murders the entire breeding-age population (and all the children) of a colony planet, just to create an army of Protector-humans to fight the Pak, and burns the entire Martian species to death just on the statistical offchance they're a threat.

That sentence would be all a right-winger would need to prove charges that the left is paternalistic, elitist, and morally myopic.
