She had a completely exceptional experience with fascists making an accomodation for her disability and made the mistake of assuming that experience was representative of the right. But I think the core of her point, that the left doesn't make sufficient accomodations for immunocompromised people, is correct. Some of our immunocompromised comrades on this site have talked about having the same problem, they couldn't get organized because local DSA or other orgs' chapters didn't want to ask people to mask up (or wouldn't enforce the mask policies).
She's making a hasty generalization to argue something that is itself very reasonable.
