MQM is worse than Taleban [split: Taliban group attacks Christian settlement..]

completely agree, on both the MQM question and the Swat question.

If the Taleban became a political entity rather than a military one, and tried to get their agenda through civic/political means, there would be no harm in supporting them.

As it stands, they are actively fighting Pakistani state forces and attempting to expand control through the use of force in different parts of Pakistan. There is no comparison of that with MQM, atleast the establishment party that MQM represents today.
