This is an appeal to users with the privilege to retag questions, i.e., everyone with a reputation of 500 or more.
Questions that reach our site via migration from stackoverflow.com will almost invariably feature the latex tag. Some of those questions will receive answers, while others will be closed as duplicates. However, the latex tag should be removed without exception, because even a closed question featuring this tag allows users to apply latex to new questions which is Not A Good Thing.
Bottom line: If you spot the latex tag, remove it (and add appropriate tags instead).
