Majority of the world uses YYYY-MM-DD. Day 1st makes no sense. If you need the month or year it should come 1st. You need to zoom into what you need not select from any number of months with the same day. That would be like putting time with seconds 1st.
Being an accelerationist makes even more your fault. It is bullshit the primary was skipped, but no progressives even tried to run there so you would have a similar choice.
