Help Limiting Content Based on User Segment

I am wanting to limit specific content on the homepage based on user segment.

I do this based on tags in a different area by using this javascript:

    var userTags=HelpCenter.user.tags;
      //check if any tags are returned. If no tags defined, print to console. 
      if (userTags.length!=0)
         {
         //if tags are found, start iterating through using a for loop.
         for(var i = 0; i < userTags.length; i++ )
            { 
              //check for the require tag. 
               if (userTags[i] === 'emergencycontact')
            {
                  //unhide link
              		$('div.emergencylink').show();
             			$('div.nopostrights').hide();
               } 
               } 
         }
});

Anyone have thoughts on how I can achieve something similar for an organization or user segment? I really don't want to manually tag 325 users.
