The ironing of assuming the worst, that someone is ableist before using dehumanising language by referring to people as slime. Cant beat it. Dude was temporarily injured anyway.
Every person ever has an excuse to ditch trollies of varying validity. No one would ever answer “because I’m a lazy, inconsiderate arsehole” if asked why they left it. Which can easily explain people assuming he’s one of said people and the downvotes. As someone who’s disabled would say “Im disabled” or something to that effect, not “I hurt my knee”. Much more likely than they hold the physically disabled to the same standard or are assuming “everyone who’s disabled should have an aide”. Get a grip.
