It's easier to see dark text on a light background for people with astigmatism.

Most things work fine with black on white terminals.

If your software does something dumb when my theme switches to black on white during the day then I am just going to avoid using it...

Accommodating terminal colour schemes, however crazy to you they might be—white on black, black on white, dark brown on off-white Solarized-style, etc.—is basics of TUI design.

Personally I alternate between light on dark and dark on light (the latter sometimes together with OS-wide colour inversion feature).

> People who use white themed terminals are psychopaths anyway

Dark background is hell for anyone with astigmatism. It’s fine with 80x24 (vga text mode), but for anything higher feels like light needles on the retina. With astigmatism everything that is bright and small is duplicated, which means small characters is very difficult to read.
