Today, a user contested the closure of his question with this comment:
And yet there are opinion based questions all over this site. There is even an 'opinion' tag already.
And he's right, there is. There are currently seven questions so tagged, mostly run-of-the-mill and non-descript, and none but would be improved by the removal of the tag.
Let's burninate opinion, please (meaning: remove and blacklist it). We don't need to arm future OPs with further excuses.
