You know, I agree with you here in practice, but not in principal. What does it mean to respect an other’s choices in a democratic election? First, I think that there must be a differentiation between those internal to a polity and those external to it. Also, I think that there can be a false idealization of the results of an election (or even more so a revolution) as “the choice of the people.” Also, I think that while on some level there needs to be a recognition, that, whatever the social, economic and political constraints on the outcome of any decision making process, some form of collective selection took place, but how far should we incorporate it into our understanding of and behavior towards that entity?
I doubt you would argue that one shouldn’t sanction or boycott Israel, because you have to accept the decision of the Israeli electorate in its selection of the Olmert/Peres/Peretz Trinity.
