Significance of Religious symbol on AIADMK leaders

"The break-away group by lead by MGR was half asthik and half nasthik. Though they have the name of Dravida Munnetra Kazhagam, they followed the Asthik route. They visited temples etc. They never antoganised the Brahmin community. So the followers of MGR DMK are having all the symbols on the forehead." -- B V Raghavan.

Have always wondered -- Was DMK ever a full DRAAVIDA munnetra kazhagam? Wasn't it, isn't it just a Thamizhar setup? Are the majority of members Kannadas, Telegus, Malayalis?
