Well, the way I see this is that unless a WG is fucking multiple civvie partners unprotected on a daily basis, then it's not the same as them being a prossie who offers BB and potentially fucks multiple virtual strangers unprotected on a day to day basis.
Where doing porn and shooting unprotected sex scenes whilst also escorting fits into this is a bit more vague I suppose. I personally feel that it's up to a girl to decide what risks she wants to take for the reward she'll get, and how she see's fit to mitigate against that risk, as much as I feel the same applies to me as a punter. I wouldn't personally rule out fucking a pornstar on the basis that she does unprotected scenes, but I wouldn't blame other punters for doing so. I would however look at her reviews very carefully and consider whether she's somebody I'd want to punt very carefully. That's not mentioning the overinflated prices most escorting pornstars charge, which has so far been the primary thing that's put me off them.
As for 'demonising' bareback. Well, I don't think that's something I personally do. I accept that it's something people do. Some weight up the risks and make the decisions they do. It's just not something I would do with a prossie, and try to avoid prossies that do do it with punters, as much as I accept that they could be doing it all the time in the private life, or under the table. At the end of the day you're probably always only 2 or 3 steps away from fucking somebody who has fucked somebody else, who recently fucked somebody else bareback. I try to keep that to as many steps away as possible when choosing a prossie I want to fuck, but I don't kid myself that that isn't more than likely a reality of things in most punts.
