No.
It tells us that people who are mentally ill are about as violent as the general population unless they also have substance abuse.
> it also says this is not to be used as a baseline for studies but if Schizophrenia is commonly co-morbid with substance abuse then pointing out that mental illness doesn't increase violence by much seems like a red-herring
When trying to predict risk of violence knowing that someone has schizophrenia tells you almost nothing. Knowing they have substance misuse tells you a bit more.
And knowing that people with schizophrenia are not more violent than the general population means community treatment is easier to provide.
thats a 2.5 difference in patients with schizophrenia compared to the general population

That is simply not true though. Substance abuse changes the rate at which it happens but Substance abuse seems to have a high comorbidity with Schizophrenia and while the rate is significantly lower when there are no substance issues it is still higher. Substance abuse, per the link you provided, creates a 3rd and fourth population subset (1: schizophrenics 2: neurotypical 3:Schizophrenics with Substance abuse 4: NT with Substance abuse) Which after your response, seems like you're being intentionally misleading in order prove your point.
There also does not appear to be a definition for what they define as a 'substance abuse comorbidity' Looking it up: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2669586/
"Schizophrenia Patients Report Consistently Higher Rates of Substance Abuse Than the General Population, Notably With Respect to 4 Licit (Nicotine and Alcohol) and Illicit (Cannabis and Cocaine) Substances"
