I don’t think there is only one right way to do anything. I think a crowd that big protesting gets more attention because you can’t say it’s just a “crazy guy” out there protesting. It’s probably not something I would do, but that doesn’t make it wrong.
Just this week I met with our county commissioners to ask that they stop allowing the JWs to leave literature in the county complex. Every time I go in there there are Watchtower and Awakes - they shouldn’t be allowed in a County Building. I made my case, they agreed. And now no more literature in the county building. (They are not going to allow any religious material even though only JWs were leaving their garbage there).
