hmm. it seems he is sorta affecting u only? if yes, then maybe u should talk to him one on one, since its affecting only u, if u can't work something out with him, then u might want to talk to ur bandmates. if the bandmates feel the same as u on the issue, then its time to let him go i think, unless u guys manage to talk him around.
in any case, there are bound to be other drummers, or someone u might be able to psycho into learning drums lol. for eg, u mentioned X japan, just let the dude watch some of yoshiki's action and u're set. lol.
not to seem like im stereo-typing or anything, but there IS a large portion of such singaporeans around. they like to so called, "put you down" in front of others. by "how-lian'ing" in front of others, they gain glory for themselves and climb on top of ur head. personally, such people are not worth bothering urself with, if they tick u off, its best to withdraw from his life.
p.s. in the event that he doesnt listen to u, nor ur bandmates, and yet u think hes too good to let go, then just go learn drums and how lian back at him lor :twisted:
