This basically makes the opposite of sense. There is such a thing as taking retro-ism too far.
Now, you may have had a point if you were talking about games on the Apple II and similar era 8-bit machines, which sometimes used the inherent quirks and flaws of NTSC/PAL TV to create new colours, by "smudging" pixels of different colours next to each other. But in reference to 68k and later Macs and CRT monitors vs LCD monitors, this is either nonsense or a very personal aesthetic preference.
Personally, I like to be able to see.
This on the other hand is a real factor - LCDs having a fixed number of pixels, they can't necessarily rescale another resolution cleanly without jaggies and oddness showing up from the mismatch of dot pitch. That's if they even rescale.
