When you say, "The content of the article is not the issue," I hope you are speaking for yourself.  For some of us, the content of the article is the only issue.  I've been through this same thing on many articles, including al Qaeda.  In the end, it didn't matter what people thought of me.  The only thing that mattered is that the NPOV tag was removed and has stayed off ever since.  We finally have an article for al Qaeda that conveys information and is stable.  That same thing can be done with terrorism.  There are only a few people here who are trying to keep terrorism undefined.  If we concentrate on the article, instead of letting them confuse the issue, we can get the job done.
I have proposed this definition, not as something perfect, but as something that conveys information—-a starting point.  The purpose of a definition is to convey information, so that much is a bare minimum.  I think my proposal is a step in the right direction because it more closely matches  for what I believe a great article should encompass.
