I wasn't around when this situation occurred and will leave the moderator who was dealing with this to reply if they so choose with regard to the lock. However I want to remind users that: 1) Even if you don't agree/like an answer to your question we expect users to remain polite toward each other at all times. You don't have to agree, but you do have to remain respectful. 2) Users do not have the "right/power" to "demand" their threads to be closed. We have never practised that form of moderation and do not intend to. We lock threads typically based upon continued hostile/argumentative behaviour by users where its clear that the thread is not going to go back on the rails or where there's already a fight happening and the thread is just a continuation of egos bashing against each other. There are rare occasions where a request to lock will be performed; but its on a case by case basis and not something we typically do outside of unique situations.
