Since Chris said "fascism" isn't in play here with BOA, who am I to argue?
So let's go back to 1920s Germany and chart the rise of some real fascists. "Just a bunch of beer house cranks," it was said. "Let 'em be," it was said. "They're just having some fun; what harm can come of it?," it was said.
Then, lo and behold, they started bullying folks around, but hey, what's the problem? There are still hundreds of other political parties to counter these clowns. Aren't there? Nothing to see here, move along. The Beer Hall Putsch failed, that idiot Hitler is sitting in jail. "What, me worry?"
But then these "beer hall cranks" started using more directed violence (guns, blackmail, extortion, etc.) to gain a foothold. And one day Germany woke up to find Nazis in an unassailable position that they then used to seize the government in order to coerce and to compel. And then we got real concentration camps....
A similar story tracks the rise in Russia first, of the Bolsheviks, and second, of Stalin. And what did we wind up with there? Famine, the GULag, the Great Purge.
But yes, let's just let the cherished principle alone. Let's just say there's never a point where a threshold is crossed.
This is what I meant when I said that one has to have a bigger picture in view. Libertarian principle is all well and good until such time as it isn't. And we are at (or soon to be at) that point of time. We have small numbers of people wielding incredible amounts of power (in this case, via financial leverage) in order to behave in what can only be described as a totalitarian manner. Be it BOA, Mastercard, or whomever. If you're talking about a small local bank that wants to espouse a certain political/ideological position, I'm all for it as I can shop my money around. But "scale" does matter; the local bank doesn't have nearly the leverage of these behemoths.
Further we also see the boards of these mega-, highly central and influential corporations (in other words, numerous small bands of people) colluding with ideologically similar state governments (New York and California immediately come to mind). Whether this is technically "fascism" or not, the practical result is fascism. With government becoming increasingly invasive and controlling and with everything financial being forced down the digital highway (as in, no cash just electronic) we (that is, the dissenters) are at significant, additional disadvantages.
This shouldn't be hard to see. Especially for a libertarian. But I guess when ones holds to a principle blindly one is, in fact, quite blind.
