Also hoping that all of you knew I don't really believe that.
But, that way of thinking leads to danger. I am still weeding out undesirable personality traits and this is one of them. I apologize for that post.
No, we didn't know. And some of us will never believe it, regardless of your explanation. Posting online unfortunately removes tone from statements, so it's hard to tell if someone is kidding or deadpanning or serious. Sarcasm is sometimes difficult to detect in person, and virtually impossible to understand in a written statement from a stranger or infrequent acquaintance.
Regardless, if you didn't mean it you still said it. That doesn't just affect the women and men you (jokingly) insulted. It affects people who have negative feelings about women in general. It supports their hateful beliefs.
Maybe I'm sensitive right now after reading, daily, anti-female sentiments from "leaders" throughout our country. Actually I know I'm sensitive. I have a decent sense of humor, but it's hard to maintain when you're repeatedly told that you're inferior and don't count as a human, and then someone like you makes an offhand remark like that.
If you're still reading, maybe read
this. While I'm not saying that your statement is as damaging as this, the principle is the same.
