And if it was, it is poorly written.
Well, you know, if Sheldon writes that he thinks something is “appropriate†as a tactic and you respond to him by concluding that he thinks it is “inappropriate,†or if he says that “a sit-in at a private lunch counter†categorically is “a trespass,†and then goes on to defend sit-ins at private lunch counters, and then you interpret him as “not allowing trespass against the private property operated by bigots,†then I’m not really sure how much better writing could possibly have helped you.
He also believes (this is the point of the closing paragraph that I assume you’re referring to when you inaccurately summarize Sheldon’s view as being motivated by “economic reasonsâ€) that in the actual historical context of the Jim Crow South, white store owners — as the economic beneficiaries of massive racist violence, and the use of this violence to dispossess black workers and suppress competition from anti-racist alternatives — may not have had any really legitimate claims of ownership in the stores that they controlled. Now this is it seems to me an interesting view and in fact it is exactly the view that you claim to think an anti-capitalist Anarchist ought to hold — that the “private property†operated by bigots is (at least in that historical context) not in fact owed any respect, that their private property claims in that context have little or no ethical significance for the kinds of protest you can direct against them. Yet you interpret him as holding exactly the opposite.
He does not hold the opposite. But his defense of nonviolent trespass is in any case not based on that claim; it would hold up even if he rejected it. It is in that sense a broader defense of the legitimacy of sit-in protests and similar forms of trespass than the one that you offer. He spends the entire article up to that very paragraph arguing that even when a sit-in at a private lunch counter does count as a trespass against the legitimate owner of the counter, that’s still perfectly compatible with the kind of nonviolent confrontation that Sheldon (following SNCC) is defending. If it turns out that there wasn’t even a trespass worth discussing — because the “owner†did not really have legitimate proprietary rights over the counter — then that’s just gravy.
Perhaps you think that this is not clear from what Sheldon wrote, and if it’s what he meant, he should have said so more clearly. No doubt we could all be clearer. But it seems to me that when he explicitly tells you that he’s OK with trespass as a protest tactic, when he phrases this in the form of a simple question-answer (“Isn’t a sit-in at a private lunch counter a trespass? — It is.â€), when he states that his argument there is not dependent on, but is only “buttressed†by, the paragraph that follows, etc., and you come away from this with the conclusion that you did, that sounds to me more like motivated misreading than it does like bad writing.
