folk who promulgate hate-filled ideologies need to be aware that their words will fall on the hinged and unhinged alike.
This was the point I tried to make earlier and got deleted - I'm not sure why. When an ideology, and the concept of killing people as a terror attack in the name of that ideology, is out there, is talked about on the internet etc, it may influence people who are mentally unstable and may become obsessive or violent in a way that is contributed to by their mental illness. Of course that doesn't mean anyone with an MH condition is violent or likely to be violent, I'm included in that myself and I don't think my anxiety problem/ former PND makes me any more likely to be violent than anyone else - but schizophrenia does have as a known symptom, feeling paranoid and under attack and sometimes having a compulsion, or a sense of being instructed, to attack others.
I really don't think it's dissing everyone with MH problems to understand that. It's the reason people suffering from schizophrenia who have killed people are sometimes understood not to be fully responsible or are sent to a secure hospital instead of prison. It's the reason there's supposed to be a system of sectioning and secure residential care for people who might pose a threat to themselves or others because of particular types or manifestations of mental illness.
Guess I might get deleted again but I do think this is important to understand. It's not just fully committed ideology-driven terrorists who are dangerous, but people who are influenced by them when in a vulnerable state. The degree of direct responsibility is probably unique in each case.
Re women, it does happen but there's probably a combination of reasons why it's much rarer, to do with female biology, socialisation and societal reactions to mental illness in the two different sexes.
