I recently voted to close a question on SO, and thought I could be helpful by leaving a comment explaining why.
I was slightly taken aback by the hostile response to this, both from the OP and the user who answered, as I was genuinely trying to be helpful.
What's the best course of action in this scenario? Should you respond to comments defending how you placed your vote, or just let it go? Also, was I correct to vote the way I did?
I am asking because if I see a similar question in the future, I would probably vote the same way, and want to make sure I am voting/understanding what's on/off topic correctly.
