What fallacy is this

From here:

Amid this seemingly endless political crusade, one notices a certain clown-car quality to the LGBTQIA2S+ coalition, which attracts a lot of people who are daft, demented, deranged, bonkers, berserk, off their rockers, nuttier than a Snickers bar, a few fries short of a Happy Meal, and cuckoo for Cocoa Puffs. It’s a coalition of crazies, blurring the line between the gay-rights lobby and the mental-health lobby, if not obliterating it altogether. Consider a few recent incidents:

In March, a young woman named Audrey Hale, who had recently begun identifying as transgender, calling herself by the male name “Aiden,” went on a shooting rampage at a Christian school in Nashville, killing three children and three adults before dying in a shootout with cops. Police said Audrey/“Aiden” left behind a “manifesto” that might explain the otherwise mysterious motive for this massacre. However, authorities have refused to release the killer’s “manifesto,” perhaps because its contents might reflect badly on the transgender community.
The actress formerly known as Ellen Page disclosed in an interview last week with the Los Angeles Times that she/“he” had decided to undergo a double mastectomy (“top surgery”) after an episode of deranged behavior while isolated in a Nova Scotia cabin during the COVID-19 pandemic. Page began “hearing voices in her head and engaging in a brutal round of self-mutilation, including punching herself in the face,” prior to deciding to become transgender, calling herself “Elliott.”
Last weekend, a dentist was stabbed to death in his $2-million home in Virginia Beach. Police arrested the dentist’s 34-year-old son Michael, AKA “Norah” Horwitz, who had performed as a drag queen in Seattle before declaring himself/“herself” to be transgender.
Perhaps these are merely random incidents, and don’t constitute evidence that the LGBTQIA2S+ movement is giving rise to violent craziness. On the other hand, if you’re concerned about such a trend, your concern can’t be dismissed as an irrational “phobia.” For many years, I’ve been warning about the seemingly widespread insanity in our society by repeating a simple phrase, “Crazy People Are Dangerous.” Of course, this exposes me to accusations of “stigmatizing” mental illness, but that’s a trivial hazard compared to the risk of being gunned down by some poor kook driven to madness by all this “diversity” and “inclusion” talk.

The fact that the writer picked a few atypical and outrageous stories looks like a good example of nutpicking fallacy and overextended outrage . 

There's also stereotyping (the fallacy) when they classify all LGBT people as mentally ill, and all mentally ill people as being dangerous.

Until the reply to Trevor Folley's question about what you thought might be a fallacy, it just seemed like a few statements about a few individuals, accompanied by an implied assumption or two (e.g., the authorities' reason for not releasing the manifesto).  The idea of a rant crossed my mind.  As statements, they're neither fallacious or non-fallacious although they might be true (accurate) or false (inaccurate).

If the intention is to present an argument along the lines of:

P1 – here are some things that have happened recently

P2 – these things are all undesirable

C – Therefore, transgender individuals are insane and a problem to our society

... well, things like nutpicking fallacy, stereotyping (the fallacy), fallacy of composition, overextended outrage , among others seem to apply ... along with non sequitur for the missing link between undesirable actions and insanity.
