Has MCA changed since Tan Siew Sin's time ?

By continuing to actively campaign and securing Chinese votes for Umno in general and by-elections as in Batu Talam, the ranks and files of MCA in fact serve to legitimize Umno's ideology and policies that are detrimental to the struggle for true national unity as well as the honour and dignity of MCA itself. What has MCA changed in essence and its unequal relations with the Unmoputras as prevailed in the time of shameless capitulationists like Tan Siew Sin ?
