Because it apparently lulls some people into thinking they have done something meaningful.And this is worse than not even wanting to do something meaningful, or anything at all? Nonense.
Talking about it endlessly here accomplishes two things: jack, and shit.
Talking about it "endlessly" is just another strawman, right now we're talking about discussing it at all, vs. discussing it not at all, because realizing in what belly people live is not interesting enough for some.pond.
If talk achieved nothing, corrupt authority throughout history including today, wouldn't be so fucking terrified of it, they would dare to shut up for a second, and let the "narrative" unfold itself, instead of being dictated. The emperor is naked, and collectively realizing that is not only half the battle, it's 90%. Unless you're suggesting to go off and just assassinate people, which would backfire, I don't see what one could do without talking about it: Before anything can be done, people need to be aware, and once they're aware, what will be done will also depend on them.
