Particularism doesn't avoid Huemer's version, because it follows necessarily from the principles given, which particularists should accept--if they're like you--while consequentialists shouldn't.
The particularist doesn't think that all principles are false. For example, they need not reject transitivity, nor think that the statement, "It's wrong to take actions that cause unimaginable suffering for the sake of trivial benefits, while violating rights, reducing virtue, increasing vice, decreasing desire fulfillment, and decreasing everything else on the objective list."
