Remesmee and that other half human kid. Only because they're both mixed with average mortals.

Mudbloods have no wizarding parents or grandparents so I don't think they can be compared to Renesmee in terms of being half of anything. If using the term mudblood in a derogatory term, then Renesmee may fit that description. A lot of characters in Twilight (Sam's pack) didn't really like her, much like how pure bloods don't really like mudbloods. I don't know who I would compare mudbloods to in Twilight.

I think that mudbloods could be compared to veggie vampires in the fact that both are different from most of their kind, since most of the wizards/witches are probably either pure-blood or half-blood and most of the vampires drink human blood.

Aside from the whole thing about what we feel about her, I actually think this is the one most likely to be stigmatized.

The veggie vampires are still accepted reasonably well- this is shown by the respect they get in the baseball game- and the werewolves are another side, not a break-away group or anything that mudbloods can be seen as.

That's true.

I just changed my answer from veggie vampires to Renesmee. Since, the veggie vamps are accepted quite well and the mudbloods are not accepted very well at all (due to the Pure-blood mania).

yeah because shes someone with a different backround, but the politically correct term is muggleborn.

Both have no say in their parentage and are kept away from priveleges (sp?) of being a whole creature...Am I making sense?
