It is not a semantic quibble to say it's not vigilantism. The core argument is that excluding people who you think do bad things is vigilantism (and, by implication, that vigilantism is bad). It is begging the question. This is the argument. It is a bad argument. It is, however, a cheap rhetorical trick to say "it's vigilantism" to conflate the right of individuals to socially exclude people who do things that they do not like with actual crimes. It is worth noting that you elide that to tut-tut at me. The argument you're making, which is not the argument that the poster to whom I replied made, is a better but not meaningful one to me. To be brief: it has not been demonstrated that the specter of false positives is anything but noise and concern trolling. Should that change, I'll reevaluate my position. I don't expect to need to.
