Our moderator team try to apply the forum rules to any actions we apply. If you don't agree with the actions of a moderator (I'm assuming that's who you are referring to, since the admin team rarely lock threads), you are welcome to bring it to another moderator, or the community manager (jpishgar) for further review.
However, your age or past experience play no role in the actions taken. I don't know what happened, or why a topic was closed, but I would suggest reading the forum rules, and seeing if there was a valid reason, if it wasn't stated in the thread closure.
