As per the official help center page on reopening questions, it states
If you're simply unsure about the validity of the closure, the best place to ask is on the community's meta site. Asking in the meta site allows those who took the action to comment, and will help others to learn about the issues being discussed.
However when I tried to do this, my question that was questioning the validity of another one of my questions was closed as off-topic with the moderator saying that my post will not be answered on this site. Furthermore there are many questions on this site that also discuss the validity of closure of their questions, which are not closed.
