JI is a sectarian organisation, whose most of the members have Deobandi background or become deobandi after joining JI !
JI is a deobandi sectarian origanisation just like JUI (Deobandi), JUP(Barelvi), SSP(militant/terrorist Deobandi), Sunni Tehreek (militant Barelvi), Tehreek Jafaria (Shia), Sipah-e-Mohammad (militant Shia), and Jaish-e-Mohammad (militant/terrorist deobandi) !
You will hardly find any Barelvi in JI, and I'm 100% sure you will not be able to find any Shia, Ahmedi, Ismaili, or Bohri working for JI which is as a matter of fact headed and dominated by Deobandis !
In veiw of the above wouldn't it be nice if we term JI as a sectarian Deobandi organisation ??
Moreover, JI's members have been involved in terrorist activities and it was its student wing Jamiat's terrorist Thunder Squad which introduced Kalashinkov in educational institutions in early 1980s !
Therefore, JI should be considered as a sectarian terrorist organisation !
