I have vision problems which are not correctable with glasses or contacts, like many people. (Fortunately, my issues are relatively mild.) For people like me, sites with poor contrast are fatiguing to read in a way that sites with good contrast are not. For people with more severe impairments, low-contrast may push past a threshold where a site becomes unreadable in practice.

This is not exactly news, there are whole guidelines on contrast published and backed by copious research.

I understand that some people are unaware of this issue. For those that are open to becoming part of the solution when it is brought to their attention, I hold no resentment.

But for those that belligerently minimize the problem, for example characterizing the challenge as "I don't like how this website looks"... not so much.

Same with organizations that surely know better but continue to present problematic low-contrast interfaces. (Discord, I'm looking at you.)
