Absolutely true. It might be 100% legal in Florida to go creeping around following kids or old ladies or whatever.

The legal quotes sound great but they neglect one pretty crucial detail: it is up to the killer to prove that he had reason to use deadly force. It is not simply assumed that he had cause to feel that his life was in danger. And a right to "not retreat" does not necessarily impart a right to ADVANCE.
For fun, let's take (what seems to be) your interpretation of this law and alter a few characters:
In this mythical case, our neighborhood watchman is a black 250 lb construction worker. He spots a suspicious looking teen, an althletic 15 year old white girl heading home after cheerleading practice. He followers her. She phones her boyfriend and reports that she is being stalked by some creepy guy. Suddenly he is right there, in terror she whips out her can of mace and blasts him. Blinded, and now frightened because she is in surprisingly good shape, he pulls out his handgun and blows her away.
Under some people's interpretation of the law he had every legal and moral right to stalk her, confront her, and kill her. Under this interpretation he did absolutely nothing wrong. She did, and she got what she had coming. She had no right not to be followed, no right not to be confronted by this strange adult, no right to defend herself.
Except we both know that if the scenario I described had actually happened, our neighood watch hero would have been arrested on the spot and charged with murder the next day. And our cheerleader? The police would have moved heaven and earth to find her parents, she wouldn't have been dumped in the morgue for a few days as a Jane Doe. And NO ONE would be dredging up high school mischief in an effort to destroy her character.
