Why is it called a chairperson?

Sounds better than: Person running the meeting that's sitting at the head of the table person

Chairman

They sit around a lot

Want to know what's really weird?

Say "weird word" really fast 10 times! I can't say that twice :(

This is too easy. Chairman is not gender neutral. Male-specific connotations have not been allowed since 1971 when the idiotic Politically correct revolution began..
Oh no we can't have that anymore

Inclusivity is the order for anyone sitting in that chair of authority
