Its because there are all those noose reporters sitting around waiting to report on the latest noose...
I mean it... I am a rope guy. No doubt you can get by tying a knot too...But I grew up long before ratchet straps and such hit here... Shoot, I never seen a snatchem strap till just about out of high school... We used skidder cables and logging chains to pull our rigs out of the mud, and loads were tied down with chain and binders, or plain ol rope.
I know how to tie a knot. It's a thing for me. I have cinched down loads on trucks, and pack horses, and even dog sleds and pokes, all my life. I ain't a sailor, but I am close... Give me a piggin string and ask for a knot, and I can likely tie it right and know it's proper use.
I have been around knots and rednecks, heck, even Aryans, most all the way along, and I have not seen a noose tied, other than the teaching, pretty much EVER. Now, that knot , or it's close kin, is handy in certain cases - My tie down on my cowboy hat uses that knot, because it is basically a prussic on steroids, made to run on two lines... The harder the wind blows, the harder it cinches... And a similar process is used to tie a neat rope grip on a handle, with the ends tucked...
But the actual noose... made for anything near that purpose... is a fevered liberal dream.
It don't happen. Not in my presence in over 50 years.
