I think it's possible to be anti-porn without denigrating the all the people involved in it. In a perfect world we could have ethical porn perhaps, but we obviously don't live in perfect world. It's great that there are sex workers who feel liberated by their work in porn and are able to support themselves, however there are so many negative consequences of freely available porn that I don't think anyone should feel bad for thinking it doesn't belong in a healthy society. It is important to be careful about the way you explain your position on it though, lest you be branded as some sort of regressive, as you said.
