i've never seen "RESPECT ME!" ever not backfire, on any scale and for any group.
Perhaps you mean something different than what I'm understanding you to have said, but demanding respect seams like it was a key part of women's suffrage, the American civil rights movement, and the more recent push for marriage equality [1]. It is true that there are still plenty of people who do not respect those groups, but they currently receive vastly more respect than they would if they had not stood up for themselves.
[1] clearly not meant to be an exhaustive list
