I am confused about this headline:
Response to We the People Petition on the Protests in Hong Kong
It's the title of an official White House response to a We The People petition titled "Support Hong Kong Democracy and Prevent A Second Tiananmen Massacre in Hong Kong".
Is "on" a little weird? So, it is a "petition on something", not a "petition about something". Does that mean I should write "a request on something", not "a request about something" too?
