If they are really pro-democracy, they should now be campaigning for Pita to be PM. The fact that they're happy with the result if it means Thaksin returns to Thailand suggests they favour one result over another, rather than what people actually democratically voted for.
Sadly, it isn't uncommon for people to claim they want a particularl progressive thing (democracy, human rights, etc.) but really they just want the result that they favour.
