I came across this article and thinking whether the use of plural form in the following sentence is necessary
2 . Conversation Etiquette ......
This is not a time to be social and discuss politics or sports.
Why not just "discuss politic or sport"?
Why is it necessary to be plural?
Any help will/would be appreciated!
