Interesting quote from Orwell, mostly because it's from Orwell. It is internally contradictory. One cannot be both a pacifist, "intellectual" or otherwise, and a supporter of totalitarianism.

So Orwell is referring to persons who may profess pacifism, but clearly are no such thing, but partisans.

This type of remark is often used to discredit genuine pacifists, who have a philosophy which LH has just outlined quite well.

Pacifists are most noticed for speaking against military actions of their own government, which is of course the one they should have the most likelihood of influencing. When they speak against the violence committed by the other side, nobody takes much notice cause they sound like everyone else.
