Yeah I know about that 1980 act, which you are misrepresenting. It took funding away from the asylums to fund community mental health programs, general health care and social services. These people were already on the street out in the "community" in public housing and this funded more social services for them. The state asylums fought against this act as it cut their funding, even though in theory they were not being underfunded due to their lower case load with people now having the right to refuse treatment. So the crazies were already on the streets since the 1970's.

His administration repealed the Mental Health Systems Act of 1980, converting this social spending into funding into block grants for the States to use however each state felt fit. The States both Democrat and Republican didn't want to spend these block grants on crazies and simply gave up on treating the mentally ill. Vilifying Reagan for this supposed closure of mental hospitals that was most certainly not a policy of his and instead very certainly the policy of Deinstitutionalization was in place for decades before him, enjoying broad support from both parties is nothing than partisan villification from the Democrats.

John F. Kennedy said in his state of the Union address “I believe that the abandonment of the mentally ill and the mentally retarded to the grim mercy of custodial institutions too often inflicts on them and on their families a needless cruelty which this nation should not endure,” back in the 1960's. Two of Kennedy's appointees where on the court that made those decisions in the 1970's. One of Roosevelt's appointees was on it. One from LBJ as well. Jackson v. Indiana was decided 7-0. Addington v. Texas was decided 8-0. O'Connor v. Donaldson was unanimous. So how can this just be Regan's and only Regan's fault? Can't Kennedy, LBJ and Roosevelt share a little of the blame?

Still name one asylum Regan shut down, or one crazy he put on the streets. You won't because you can't. As governor of California he didn't even shut down the biggest insane asylum of them all, the State Capital Building in Sacramento.
