There are questions that are fine that they don't in themselves deserve negative votes. However, sometimes such posts get unusually high votes.
I understand that the up-vote and down-vote criterion is to vote the question that shows research effort, has good quality and few other things.
Is it ethical to down-vote if you think a question is not bad enough to deserve a down-vote by itself but also that you do not like it receiving more votes than you feel it deserves?
