Everyone on BGG who sleeves, who make fun of non-sleevers, who insist on sleeving are doing it out of ignorance not malice. A rare case of Hanlon’s Razor applying. Not once have I seen them demonstrate awareness that sleeves are bad for the environment and that they cause diseases. I’ve seen them make pro and con lists and saying “for me the pros of sleeves outweigh the cons” and those con lists have not had how card sleeves make us sick.
