Who are you to decide what other people do with their dogs? If there’s a reactive dog that doesn’t mean my well trained dog needs to be leashed he’s not the problem and I can call him back to me and hold him while the bad dog passes, if it’s legal for my dog to be off leash he’s gonna be off leash. If there’s a leash law he’s on a leash, if some asshole decides leashes should be used all the time then they’re just an asshole and who cares what they think.
