I don't want to be the one supporting them here, but that was part of the joke. They are horror movie fans who created a traditional kind of serial killer (the prostitute-murdering kind who would, of course, have misogynistic views on women), and used that to plug in their own views of the movies and shows.
Not every view espoused by Plinkett, a horrifying killer, is supposed to be taken literally from the mouth of Mike Stoklasa, even if it comes literally from the mouth of Mike Stoklasa. It's just a confusing dynamic they set up for morbid humor.
Even in Half in the Bag, they play caricatures of themselves. This Re:view series, which I haven't seen, and I suppose the Best of the Worst, are the only times where we can take their words sincerely. But they're still comedians doing jokes, so we should always look at context.
But when Mr. Plinkett says something about killing prostitutes, we're intended to roll our eyes at the exaggerations being made, not treat it as a disrespect for women. A point to be made: Stoklasa's wife used to be a regular on Half in the Bag, but she had to leave because some of the fans of the show used some incredibly disparaging remarks (probably just jokes, of course, taking the Plinkett personality too far in YouTube comments, but who knows). These guys aren't their characters, and have taken measures to protect themselves from the fallout of their comedy, but not perfectly so. We shouldn't fall into the same trap as some of their more fervent fans and take them too seriously.
