Does downvoting an answer qualify as divisive and harsh speech?

In a comment to an answer on this site I saw this: > To the folks who insist on downvoting, please note that downvoting is > extremely unhelpful and actually qualifies as divisive and harsh > speech. Do others agree? Does downvoting an answer necessarily qualify as divisive and harsh speech? I've thought of it as a form of feedback. Of course, if it is possible to elaborate and provide more constructive feedback then by all means... Does downvoting violate the precept on correct speech?
