The first kind are merely stupid, the second nefarious.
It is impossible to understand politics in the world today without grasping the fundamental fact that there exist two different Lefts. These are the Stupid Left and the Satanic Left. The two are very different, although they work together. People who are part of the first are simply stupid people. People who are part of the second may in fact be quite shrewd, but are evil and nefarious. There is no third type of leftist.
Over time, the Stupid Left has been losing its numbers, as many Stupid Leftists either become smarter or morph into Satanic Leftists, and so desist from being mere Stupid Leftists. So a process of selection is occurring whereby the strength of the Satanic Left within the overall Left grows.
Both the Stupid Left and the Satanic Left demonstrate together against the United States, in favor of Islamofascism, in favor of destroying Israel and in favor of Palestinian terrorism. But for different reasons.
The Stupid Left hates America because it thinks America promotes evil oppressive regimes around the world. The Satanic Left hates America because America gets in the way of the evil oppressive regimes that the Satanic Left promotes.
The Stupid Left denounces capitalism and globalization and supports communism because it really believes that people are poor and oppressed under capitalism but free and happy under socialism. The Satanic Left denounces capitalism and supports communism precisely BECAUSE it knows that the opposite is the case.
The Stupid Left does not know that communism produces gulags. The Satanic Left supports communism precisely BECAUSE it produces gulags and also because the Satanic Leftists presume they will be placed in charge of the gulags.
The Stupid Left wants a Palestinian state because it thinks that such a state will pursue peace alongside Israel. The Satanic Left wants a Palestinian state precisely because it knows such a state will launch a war of destruction against Israel and perpetrate endless atrocities against the Jews.
The Stupid Left opposes Israeli armed force being used to suppress terror because it thinks that terror can be resolved through dialogue and negotiations. The Satanic Left opposes Israeli armed force being used to suppress terror because it supports terror against Jews.
The Stupid Left thinks that Palestinian leaders and Arab nationalists are progressive and liberal. The Satanic Left supports the same people precisely because it knows they are Islamofascists.
The Stupid Left is under the impression that Arab states have elections and freedom and enlightenment. The Satanic Left supports Arab regimes because they want to destroy Israel and murder Jews.
The Stupid Left thinks that Israeli settlements are an obstacle to peace. The Satanic Left wants the settlers evicted or killed because they are an obstacle to the Palestinians destroying Israel.
The Stupid Left thinks the Middle East conflict is about Arab human rights. The Satanic Left knows the Middle East conflict is about suppressing Jewish human rights. They support this suppression.
The Stupid Left thinks the Middle East conflict is about land and borders. The Satanic Left knows it is about Israel's existence.
The Stupid Left thinks Israel is a discriminatory apartheid country. The Satanic Left wants Israel destroyed so that the Arabs can impose an apartheid regime directed against the Jews and any other non-Moslems.
The Stupid Left thinks Zionism is a form of racism. The Satanic Left supports anti-Zionism precisely because it is a form of anti-Semitism.
The Stupid Left says it favors equality. The Satanic Left favors transferring power to itself so that it can oppress others.
The Stupid Left thinks animals should be treated like humans. The Satanic Left thinks humans should be treated like animals.
The Stupid Left wants socialism because it thinks that people will not have to work under socialism and because it thinks that leftists will have a lot of friends under socialism. The Satanic Left wants socialism because Satanic Leftists will not have to work under socialism, while they turn everyone else into slaves, and because they will get to shoot their friends.
