I don't know, I have a pretty good idea. And we'll never know. Like I said we can be told all types of stuff doesn't mean it's true. I think it's highly likely a radical left trans supporter with a small chance a state in the east but if that's the case it will still come out as radical left trans and we'll never be the wiser.

The ammo used was stamped “TRN” because it was manufactured by the bullet manufacture Turan.
And a MAGA saw the “TRN” stamp, and apparently thinks about trans people all day every day, and so that’s what they ran with for half a day.

I agree with you that the story of who this person is and their ideology was written before they even knew who he was.
It is unfortunate that we won't ever know the real truth, no matter what it is.
This is why the spin machine is all that matters nowadays. Trump blaming the "radical left democrats" immediately (before they even had the 2nd incorrect suspect in custody) already set the narrative.
Everyone will believe whatever suits their narrative and what their chosen media tells them to believe.
Today's world is an odd one. I, for one, am going to go touch some grass!
