Kennedy, I didn’t suggest…
Kennedy,
I didn’t suggest that descriptions like “Du Toit is using bigotry to excuse aggression against innocent third parties” should be presented without an accompanying argument against the bigoted premise, did I?
What I think I have argued is that that is an accurate description of the structure of du Toit’s argument, and that it can be part of connecting your exposition of the argument to your criticism of it (in this case, as a transition to the general reasons for rejecting political collectivism), so there’s no reason why describing an argument as resting on a “bigoted” premise entails not addressing the argument on its merits. It’s just a description of the structure of the argument, which may or may not be accurate in a particular case, and which, if accurate, can be part of addressing it on its merits, by pointing the way to the rest of the argument.
How much of that argument needs to be spelled out and how much can be taken for granted depends on the audience that you’re addressing; here I’ve only mentioned the general reasons against political collectivism rather than spelling them out, or spelling out their application to this particular case, because I’m not trying to convince du Toit (or other border creeps) of anything at all about immigration at the moment. I’m trying to convince you of something about something else, and I figure you’re already acquainted with the arguments that I’m using as examples.
