There are many assumptions in that statement
1. Women do not have a range of paranoia, with some more paranoid than others.
2. Brown, being a woman, is like the average women in terms of paranoia.
3. She is not justifiably fearful given the threats, she is irrationally paranoid.
4. It is her decision to ask for more protection, not the recommendation of those charged with her protection.
5. Paranoid is a clinically identified psychological abnormality. If females are by nature paranoid, then being a woman is a disorder.
