«Against this, the secular Right have nothing positive to offer. »
Agreed.
At the end of the day, «religion» is only a word. It is true that Leftism is not a true religion in the sense that it is only an excuse and rationalization for evil (selfishness).
It is a religion in the sense that it has blasphemy laws and we live in a theocracy of the Leftist religion. There is no separation between Leftist religion and State, but the main goal of the State is to enforce and evangelize the Leftist religion. The laws are based on Leftism, the same way the laws are based on [the other monotheist religion] in an [other monotheism] theocracy.
Saying that Leftism is a religion is the first step to awaken people that have been lied every day since the time they were born. Because, otherwise, Leftism (freedom, equality, non-discrimination, democracy) is presented as a neutral: as the obvious truth and decency. All the other worldviews are labelled as «religions» and hence, partial, private and debatable. But Leftism is not debatable: it is only the basic truth and decency that can be seen by anyone whose brain has not been washed with religions.
It is a useful weapon with my students, who have been brainwashed with school teachers that are fanatic zealots of political correctness. After telling them that Leftism is a religion, I add «and the goal of life is to find out which religion is true and follow it». Of course, I spend the rest of the course attacking Leftism in one thousand ways.
I cannot go further because I would be accused of violating the neutrality of the University. The professor of Philosophy teaches Leftism every day, because it is seen as neutral. I cannot teach Christianity because it is seen as partial. Do you notice a pattern? Saying Leftism is not a religion makes it entitled to special treatment.
I understand that you write for people like me, who are outside the official discourse. If you say that Leftism is not even a religion but a pseudo-religion, like you do, this means a step forward in the discovery of truth for people like us. Of course, you are right, but saying that Leftism is a religion can be a useful weapon in the first stages of deprogramming.
