I think you are equating those with disruptive. Peaceful doesn’t necessarily mean non-disruptive. Peaceful and disruptive protests can certainly still make people in power sweat
Strikes are peaceful and disruptive
Shutting down freeways can be peaceful and disruptive
Boycotts are peaceful and can be disruptive
Sit-ins are peaceful and can be disruptive
etc.
Not that 3.5% is necessarily an iron-clad guarantee
If the filibuster is removed, it is also possible to get through with 50+VP as tie breaker or 51. The filibuster being removed is not as unlikely as you may think since Republicans right now are getting closer and closer towards defacto removing the filibuster. There currently are narrow ways around the filibuster (reconsideration is one big one) that are supposed to have a bunch of limitations, but they are testing the waters in ignoring violations of those limitations. The senate parliamentarian is the one who makes rulings about if something violates their clauses, but their opinion can be ignored by a strict majority via the “nuclear option”
A month ago, Republicans used the nuclear option to ignore the senate parliamentarian ruling that the Congressional Review Act would not allow them to skip the filibuster to remove California’s EPA waivers (see here).
As I write this Republicans are currently trying to play another different a different trick about some of the stuff in the Big Beautiful Bill. Dems have been challenging a bunch of provisions and getting the parliamentarian to most of the time rule they are in violation of the Byrd rule. But they are also trying to challenge the whole bill as violating the Byrd rule’s limit that a bill passed via reconsecration cannot increase the deficit over a ten-year period. Republicans are playing an accounting trick to claim it doesn’t. They know the parliamentarian is unlikely to agree with them, so they are currently trying to prevent dems from even being able to ask the parliamentarian about it
