Is it normal to think that porn actresses are just sluts?

I always thought that all they do is degrade themselves in front of the camera. And yeah, I enjoy watching porn. But still, for me it felt always like this, every single time I tried to find a reason or justify their job. Those girls are bitches aka whores aka prostitutes and they deserve not too much other than cock, and the guys are just doing their lifetime job of inserting it in the hole.
