I noticed this Answer coming up in the review queue and wanted to ask for some concrete guidance on Delete Votes Vs Downvotes.
As per a lot of the comments on the answer it's clear that a number of people feel that the answer does not accurately reflect the reality of the difference between Excise Duty and Customs Duties.
However, deleting the answer seems like an over reaction, down voting and possibly commenting (commenting seems more common than downvoting), seems like a better way to progress, it allows both the answer and the comment rebuttals to stay around. Refuted answers can provide users with no current knowledge more information that a straight up "correct" answer.
