I see you as the myopic here; by pretending you only have to the long term stuff (votes, campaing) and that the short term stuff doesn't matter or shouldn't be done (like the employees complaining in this case) like these kind of protests live in a vacuum; when artists in the 50s refused to play in segregated crowds you think they didn't ALSO advocate for the long term stuff like voting for congressmen in favor of less racism? Absolutely nothing lives in a vacuum, and creating noise against ICE like they are doing in this case can help even more than doing the politics part themselves, because the exposure they get influences other people reading such news.
