This means that the left's activities are motivated and actuated by its animus toward the values and ways underpinning what we call "Western Civilization." Driven by its antipathy to it, the left's ultimate objective is nothing less than the subversion of this socio-political system.
This fact is not always easy to discern, since most of the time evidence of anti-western animus is not readily obvious. Nor is it admitted to by most of those who harbor it. It is especially difficult to detect by observers who are not aware of its existence in the first place. To conceal their true motives, those on the left have consistently claimed that their deeds are inspired by love, compassion and other such noble motives. Many well-meaning people either believe such claims or at least give them the benefit of the doubt. They do not carefully analyze the left's actions and thus fail to recognize their corrosive effect on their society and civilization at large. What makes it difficult for unsuspecting people to see the truth is their inability to imagine that the activities some of their fellow citizens could be fueled by hatred of their own culture and community. Then there are those who sense that something is not quite right, but they lack the intellectual framework to properly grasp or articulate what may be wrong with leftists and their works.
Only a relatively small sliver of the left is honest about their true feelings and goals. There are few who openly confess their aversion to the Western way of life and their desire to do away with societies that practice it. These honest elements, however, are usually seen only as an extremist minority residing on the far fringe of the spectrum. But this is not the case. The haters of the West do not constitute merely some small clique on the left. They are only more sincere than their ideological compadres who disingenuously conceal their aversion toward western ways under the false façade of love, compassion, tolerance and such. The truth behind their motives is actually the exact opposite of their claims.
