Having a thread closed when you’re in the middle of making your points, when you’ve just made them, or the thread is otherwise useful or interesting can be very annoying, I’ve been there so I sympathise.
On the other hand whether every decision is faultless or not, it’s probably an indicator of a good time to stop and take a breath, and let it (both the moderation and the original issue) go.
Just take the opportunity to look at in a positive light as helping preserve one’s health and sanity from needless arguments.
