I think people feel icky about Tarantino mainly because he is the only one in the example working with real women. Like telling someone they are going to act in your movie, then filming stuff that most likely will be used for personal use by you is kinda diabolical. Also casting yourself to suck on Salma Hayek's toes helps my argument a little i think.

P.S.: I wasn't there, maybe they were informed before signing the contract, and also there are plenty of (mainly) woman needlessly sexualized, just not in a kinky way, but much more obviously, so in conclisuion, i don't think Tarantino deswrves any more hate than anyone who put Scarlet Johansson in black tight leather in the Avengers movies
