Mercedes Carerra was just a regular porn star, not known as a fetishist, and she was dabbling in right wing grifting around 2015. I think Ralph is just playing off of Paul Joseph Watson's tweet. Paul is making a tongue in cheek joke about how he likes her gamer gate videos and referencing her porn videos, Ralph is making a crude joke about watching her porn as well, the vast majority of which is just regular big titted milf porn stuff. II haven't looked into what transpired with the child abuse thing but that happened years after those tweets and happened in her personal life, not her porn, and to say that Ralph liked her because of those things is a big reach imo. He liked her because she was saying 2015 conservative gamergatey things online and is a big titted milf.
The line about "if she's down" being pedo code is such a reach it makes me wonder whether your whole post is a joke. You don't know people that say "if x is down"?
