Any advice on finding an accessible new computer?

My arm injuries are getting worse.

I’m planning to get a new desktop computer with better ergonomics and install either Mint with Mate or another accessible version of Linux on it. Obviously it’s hard to test Linux compatibility and accessibility in store.

I am clumsy, and often hit the wrong key, or select the wrong item from a menu, or miss the button or link I’m trying to select. I can type with my right hand, but am too clumsy to type with my left hand, let alone both at once. I am sensitive to bright lights and high-pitched noises. My previous computer, before I traded it for this one, was a Toshiba. It had a painfully bright screen, and high-pitched processor noise. I tried using it at the minimum screen brightness, with a piece of paper in front of the screen, and wearing sunglasses, but it was still painfully bright. I also took it in for repairs for the noise, and eventually sent it in for factory refurb, but it came back with the same noise.

How much violence do we face?

Unfortunately, I can't directly reply to this essay on the Transadvocate about TEPF appropriation of TDOR:

However, I think some of the stats are misleading.

"Our best estimates indicate that one out of every 1,000 homicides in the U.S. is an anti-transgender hate crime."

But many more than 1 in every 1,000 people are trans. At this point, we're probably underestimating how many trans people are being killed, and definitely underestimating how many trans people there are, and possibly comparing lifetime stats with yearly stats.

For example, when I was starting transition, I was stunned by seeing claims that 1 in 12 trans people gets murdered, while 1 in 18,000 cis people gets murdered, but I think those figures combined all these errors.
