Which is to say...yeah, that is definitely a thing :/ Though I've seen people come up with arguments for why classism is a big deal but sexism isn't, sexism is a big deal but racism isn't etc, a lot of this sort of "logic" is just sophistic window dressing for ignoring anyone they don't feel like caring about.
