What a tosser! Not communist or socialist. Just common courtesy. You may start a thread, and feel that your initial concern was addressed. But many other people, as is their right, have begun a healthy discussion related to your initial question/concern/observation. So yes you have the right to close down a thread you started whenever you want but, why??? If it has run its course it will fall off the bottom of the forum threads page, if it is still humming along, why not let it.
