There is absolutely no automatic cross-over between being assertive and being creepy. That some men don't want to live in a world where women are allowed to make a choice about whether or not they want to accept their advances is, however, fucking creepy!! Women are not sex/love dolls that you can just access at will because you want to. They are actual autonomous human beings. I know you know this, but saying that some men don't want to have to accept that as if it's a reasonable thing just makes my skin crawl.
"I don't know how to talk to women" is not an excuse to act in entitled or objectionable ways towards them. I don't know how to make Duck a la Orange, but I could learn.
