Gender dysphoria doesn't make people assassins.
Furry stuff doesn't make people assassins.
However, there are engineered echo-chambers populated by both types of people. These echo chambers align with the left-tribe and they are incredibly extreme.
These communities (different from a trait) are at this point clearly and obviously over-represented to a huge degree in the rolls of mass shooters and assassins.
The thing is, people who have been paying attention have always said it's the "community", the "discourse", and the "dogma" that is dangerous. Not any particular mental issue or sexual interest.
In other words, they are dangerous. They are dangerous because they perceive (in their socially constructed delusion) a world where people want to kill them.
They don't hide this, they say it all the time.
"I can't talk with someone who won't acknowledge I exist"
"trans genocide"
"my existence isn't political"
"they want a world where we no longer exist"
Emotions react to perceived fact. Any human being who genuinely thinks the world is increasingly set on killing them (or a loved one) is going to react with fight or flight.
The result is predictable, and I'm not just talking about the violence, I'm talking about the suicides and the shattered families.
If a social phenomenon is in mechanism and result like a cult, we should call it a cult and respond accordingly.
