Generally speaking, states with straightforward open carry don't harass and demean upstanding citizens in this way. But, many states allow it ... the "scream bloody murder" demeaning, I mean. In such a place, be aware that you might well be taken down by police on a "man with a gun" call, and forced to "explain yourself." In some states, you're committing a crime by inducing fear in others, even though you had no such intent.
Know your state's laws.
