You could also use the select tool to draw a single circle, then go to the Select menu and click Border which will create the outer and inner selections with the width you specified between them. Much easier than selecting a circle and de-selecting the centre hole.

Do you understand how bitmaps and raster drawing works? Everything is represented as a 2d array of pixels. The circle selection before you paint can be moved/scaled/etc and then when you actually want to draw the circle trace the path with the appropriate thickness and use antialiasing if you need to smooth it.

If you want to make vector drawings, take a look at InkScape. GIMP is the wrong tool for that, so use the right tool for the job if that’s what you want to do.

What’s the problem with making a circle with the select tool and then tracing it or filling it? It’s not hard to make a circle in GIMP…

People seem to think that supporting a social justice cause somehow makes them left of centre. It doesn’t. The US has spent a lot of time and money trying to stamp out governments with left of centre economic policies for many decades and has framed anything even remotely socialist as full-blown authoritarian communist butcher-dictator, and therefore anything short of full capitalism and privatisation of everything is bad. They over-thew social democracies in Latin America and installed brutal military dictatorships to privatise and sell of the resources. They napalmed Vietnam because something-something commies. The US has no concept of what left-of-centre is because they have bombed, raped, and pillaged pretty much everything that resembles left-of-centre in this world. I even hear people in the US calling themselves ‘left of centre’ and then finish their sentence hating on socialism - which is a pretty broad spectrum of ideology.
