We are collecting info because:  
A) It's neat.  
B) It allows everyone to know what kind of people participate in this sub, so users can know where our biases are.  
C) It allows the mods to know which opinions truly are unpopular. For example, if 95% of /r/unpopularopinion doesn't have any kids then "I don't want to have any children" is not an unpopular opinion and should be removed
