I endorse the right to OC and don't find it aggressive, but what does raise an eyebrow with me is ostentatious OC.
You'll notice that an OC rig that's appropriate for public settings typically doesn't draw much attention. People who aren't familiar with OC tend to assume that the wearer is a detective or similar authority. But when someone carries in a way that's inappropriate, they're seen as dangerous. They're signaling that they want to be noticed, and the natural response is to question why, and whether they might be a threat. I find myself doing this, and am otherwise very comfortable with firearms, but seeing a grown man playing dress up with a firearm does cause me to wonder.
