The meta thread in question had only one answer (mine), with more upvotes than the original question, advocating the question be kept open. Noone had put forward a counter-argument, least of all an upvoted one, but the casting closure vote was clicked anyway.
I suspect this is probably simply a result of there not being a meta link to the closure discussion attached to the question in question, but this is simply not on.
- The question be reopened until the discussion is complete
- Whenever closure discussions happen in future on meta there should be a link to them on the question
