I think the behavior of Glover et al is best explained by assuming that they simply do not care about the outcome for the peoples of places like Venezuela.

For most Leftist, the real people in the world are just stage props in the Leftist own little social-political psycho-drama. They “care” about them only to the extent that their suffering can be exploited in the context of our own internal social and political squabbles. Leftist choose their positions on such issue based on their own self-interest. When they can no longer exploit the plight of the poor and oppressed they forget them.

You can see such actions very clearly in recent history in the cases of Indochina, South Africa, Nicaragua etc. Once the plight of an area ceases to have internal political ramifications they drop it like a hot potato.

I think it is time to stop looking at most Leftist as bumbling but well meaning and instead see them for the dangerous narcissist that they are.
