The merit of abstention depends on how important you think it is to defend democracy, under capitalism as it is, from the army. Already the army's intervention and civilian support for that led the constitutional court to make the decision that it did, successfully forcing early elections. A setback for democracy in Turkey.
You, as well as WSWS, say that both sides -- the AKP and the army -- are "wrong." They indeed are in the sense of both being for neoliberal capitalism and imperialism, though differences exist between class-demographic compositions of their respective support bases. Nevertheless, the one side is democratically elected, while the other side isn't, and the unelected side in this case is far more repressive toward leftists, the Kurds, the Armenians, etc. than the elected side, and that's a difference that matters.
That is not to say that there is much that leftists can do in Turkey, because Turkey, like the USA, Japan, etc., doesn't have any strong organized Left, so leftists wouldn't be able to make a difference even if they tried. At the very least, though, leftists in the West should refrain from cheering big right-wing nationalist rallies, just because they say they are for "secularism," and clarify how they function in Turkey: as civilian support for the army, which all thinking persons, from most Turkish socialists to journalists for the bourgeois media, understand. In this particular case, even the Financial Times and the New York Times got the basic facts and principles of the case correctly, so there's no reason why leftists in the West can't.
In the upcoming elections, some Turks will probably feel pressured to vote against the AKP in fear of what the army will do if they don't, which is another setback for democracy in itself. What if the elections don't go the army's way regardless? What will the army do then? The AKP, being liberal bourgeois, won't inspire the kind of response from the masses that Chavez did when his government was briefly overthrown by a coup -- needless to say, it doesn't have the sort of following in the military itself that Chavez does.
