Your right to privacy is essentially a right to determine what private moments get shared and which do not. It is not a decision you make once (at the time you become a public figure, or when you first post a private picture publicly.) It is a decision you are allowed to make with every private moment.

So this:

"Just like in Gawker's case, decisions have consequences. Don't claim your sex life is private and no-one's business (and I have zero interest) whilst posting pictures of yourself on gay cruises."

...is not saying that decisions have consequences. It is saying that people who make decisions you don't agree with have no right to privacy. You are arguing that a perceived moment of hypocrisy should somehow revoke a person's ability to make decisions.
