Yes, some might spoil their ballot papers, some might vote for the the Monster Raving Loony Party (always assuming they have a candidate in their constituency - at the 2024 General Election the MRL Party had candidates in 24 out of 650 constituencies), but they will at least have voted. If you can’t see that would be preferable to a situation where someone is elected by a tiny proportion of the electorate, you really are very ill-informed.

Andrea Jenkyns was elected by 42% of 24% of eligible voters - that’s 10.08% of the electorate, 89.92% of the electorate did NOT express a wish for her to become the Mayor of Greater Lincolnshire. If you can defend that, you really are on another planet.
