Because unlike my question yours is irrelevant. Whether I'm out every day or not, hell even if everyone is out every day, either way this "no buy day" will still remain entirely non-impactful and entirely self-congratulatory.
We need to spend less time coddling people and trying to massage away their legitimate anxieties and more time focused on having grown up conversations with people like adults about the realities of our situation - even when said reality is starker than a couple warm-fuzzies can solve.
But to answer your whataboutism anyway: daily? No sir. But I have been out in the streets, and I will continue to do. And I will continue to encourage useful collective actions while reminding you that I can only participate in the collective part of collective action, as I am not myself a monolith; critiquing individual efforts is wildly different than critiquing collective organizing effort. But to be clear, feel free to criticize me because unlike defenders of this wasted effort protest I do not believe that the mere goodness of my intentions makes me beyond criticism.
So back to the question posed to you - the suggestion that anything less than full support is the same as opposition is bullshit. First off we're leftists - we have reason, logic, decency, literally all the immutables on our side - we don't have to default to ignorance and happy feel good platitudes. Telling people that they're wasting their efforts, not prohibiting them, isn't opposition, it's respecting them enough to talk to them like grown ups instead of placating them like children.
