The actuality of Leftist morality - and that it is inversion of the true, beautiful and virtuous - is revealed by describing the double-negative reality concealed by the pseudo-positive moral 'principles' used to justify Leftist evil.
Here is the way it works:
To be a 'racist' is = not to be anti-white
To be a sexist = not to be anti-men...
You see the way it works? Leftism is oppositional, being defined as 'against' various 'evils'. Most of the Leftist 'evils' (often expressed as '-ist' or '-phobic') can accurately be described in a similar double-negative fashion:
Not to be anti-native inhabitants of a country...
Not to be opposed to biologically real, reproductively-adaptive sexuality...
Not to be anti-Christian... etc.
The double-negative formulation is a necessity for Leftism, since Leftism is indeed ultimately oppositional (opposing God and divine creation; opposing the true, beautiful and virtuous); thus its 'positive' content (i.e. what Leftists want) is protean and labile, self-contradicting and incoherent.
After all, there are an 'infinite' number of ways of opposing The Good.
To be morally excoriated by the Left, all that is required is to be against opposing the Good, in any particular respect.
Added - Double-negative denialism
For the sake of completeness, and to include two of the biggest recent double-negative global crusades. What do accusations of denialism amount to?
Climate denialism: Hatred of those people who do not regard carbon as the greatest threat to life on earth
Birdemic denialism: Terror of those who are not afraid of close proximity to human beings
Note: This idea was triggered by a post by William Wildblood, where he give a double negative definition of 'racist'.
