The fact that something is legal doesn't obligate people to do it on a regular basis. It's legal to own a silencer, but I've never gotten around to buying one. I know people who don't own firearms even though the constitution guarantees them that right.
The fact that something is legal doesn't mean that it's automatically a good idea to do it every available chance. In fact, a particular activity that's legal may not ever be a good idea for some people based on their varying circumstances. It's legal to drink per the constitutional abolishment of the prohibition amendment, but I know people for whom alcohol consumption is a bad idea. I know some people who should never get behind the wheel of an automobile because they can't maintain focus or because they have disabilities that make it impossible for them to drive safely.
And contrary to the common assertion, rights don't go away simply because they are not exercised. They remain in place for when/if they are needed. Many people don't exercise their right to choose and practice a religion, but that doesn't mean the constitution is in danger of being changed to eliminate those rights.
The more the public sees OC ,as normal, the better our gun rights will be ,IMO.
Watched a video where a guy was shot because he lost his mind about his neighbors playing loud music. They apparently did it a lot and he didn't get used to it, instead he just got madder and madder until he was literally unable to behave rationally. If someone finds something irritating, there's a real possibility that seeing it a lot will just make it more and more irritating, not less. If you think about the last time you watched the news or drove in heavy traffic, you can probably think of at least one thing that works like that for you.
In other words, I'm not so sure that's a good assumption. Some people will normalize the behavior in their mind if they see it enough. For others, they might not care either way, regardless of how often they see it. Some might have a good or bad experience and that might be the deciding factor in how they view it, more than how often they see it. For at least some, it's likely to just irritate them worse the more often they see it.
