Have these people not heard of office breakrooms existing outside of white-majority countries? I would bet that having food together in a communal setting is a team-building and fun activity throughout the world regardless of skin-color. Most likely, this was some young, introverted person who was uncomfortable being in a group and wanted to somehow bring in race into that to justify their viewpoint.
As someone who isn't white, this sort of coddling non-sense is simply infuriating. I do not want to be judged based on what I look like, and platforming/pushing these sort of views does exactly that.
They have become the very caricature of what right-wing news makes out liberals to be.
