Found via https://mathstodon.xyz/@ColinTheMathmo/114937443323984872. I didn't know it was a contentious topic whether zero was even or odd.

Zero being even is not contentious. Contention is when there is strong disagreement whereas people who are misinformed can be mathematically proven to be incorrect.

By your reasoning you could call all higher mathematics "contentious" because laypeople would come to wrong conclusions due to inexperience. It devalues the word.

Fair enough. "Contentious among laypeople"?
