The key to showing up armed is to have friends, preferably many, also armed.

It’s easy to single out and bludgeon a peaceful concealed carrier with naught but helpless spectators around and conveniently see the weapon on his person as an “imminent threat” after executing him on the street. (God rest his soul)

If the local 2A club was peacefully standing out there, the thugs would definitely reconsider violence as their first resort.
