However, I don’t think reflexive actions like what you’re suggesting will sway anybody who’s not already convinced, or really help in any other way. Disruptive demonstrations can occasionally work IRL when they can serve to convey a concern to people who wouldn’t otherwise notice it, or to assure like-minded people that they’re not alone. Online forums, by contrast, are both lacking in passersby and plentiful in tools for suppressing disruptions.

Furthermore, I don’t think you can really outpolitick a politician on this low a level. Well-motivated and well-publicized forks could work. General apathy and nonparticipation could work. Other ways of voting with your feet could also work, if you can think of one. But you can’t argue (collaborate on converging to the truth) with an opponent who’s completely convinced of their own rightness and righteousness, only debate them (attempt to expose each other’s faults to an audience). Debating a politician won’t work, because they’ll crush you. It’s a large part of what being a good politician is, after all.
