I'd venture to guess because it has an unnecessary negative tone to it. Specifically the "Sounds stupid" part. That two word postfix is unnecessary to ask the question and adds a negative and dismissive attitude to the discussion. A good gauge for any comment here is "Would you say this at a business meeting?" I believe the answer here is that the snide remark "Sounds stupid" would be left off when speaking amongst professional company.
