It's kind of embarrassing to admit but us Bengalis specially from Bangladesh are peaceful havoc loving people. It's really normal to see politically affiliated people fighting with each other by using sticks (long,short, medium size), machetes, small knives, oar etc during election time (specially in rural areas) and not everyone of them are lathi khela practicioners. Specially people living in shoal are known to use lathi/stick because dispute of "who owns what area" always goes on (nowadays it's reducing though). Lathi Khela nowadays is more of a cultural sports for entertainment than an actual widespread recognised fighting art with universal curriculum system. As the old saying in Bengali goes, "jar lathi, tar mati (the one who weilds the stick rules the land)"
