Let's expand this a little bit: LEOs don't like OC and come up with all sorts of arguments against it because it encroaches on an area that many see as a prerogative of law enforcement and not as a Constitutionally-protected right. Following that line of reasoning, they cannot, and will not, come up with logical arguments against a citizen openly carrying. Instead, they use the same emotional appeals (or a reasonable facsimile thereof) that the anti-gun folks and the out-and-out hoplophobes do.
When certain types of personalities perceive that they cannot win an argument by logic then, as stated above, they try for an emotional appeal. Should the emotional appeal be rejected and shown to be flawed by a presentation of factual evidence, then the next resort would seem to be threats with increasing elevation to the level of violence of one type or the other.
While I am not a psychiatrist (not crazy enough) nor psychologist, it appears to me that those who practice this sort of deceit, and who deceive themselves with it, are much closer to a clinical definition of mental illness than is one who, like the majority of us, routinely openly carries a weapon and regards it as a normal part of their lives. While there are those (thankfully very few) in our community who seek confrontation with law enforcement for a variety of reasons, most of us just want to be left alone to pursue our legal activities.
