The close reason given is rather clear:
"Questions on politics are off-topic as they're rarely productive or relevant to the teachings of Islam."
That question, as written, has already attracted two answers; one of which was flagged for being offensive and deleted, and the other (yours) which is naught more than blatant apologism (which is not what this site is for).
This is a pattern that is consistent with questions of this nature: They will almost inevitably attract partisan answers, apologetic answers which agree and polemic answers which disagree. Voting thereupon just becomes a popularity contest, which does nothing to forward the academic study of Islam.
It does, however, breed exactly the sort of sectarianism which has plagued this site from the beginning.
We are not a forum. We are not a site for argument or debate. We are not a site to prove other people right or wrong. We are not a soapbox for personal views. We are a site for clear, focused questions about the topic of Islam, which can be effectively and constructively answered according to the mechanics of the Stack Exchange model.
That question is not one of these.
