The key to understanding the modern Left is that it is 95% destructive, and its positive 5% is continually rotating between (for example) the primacy of equality, anti-sexism, anti-racism, promotion of sexual inversion, liberty, the environment... and others.
Which means that, in practice, the Left is 100% destructive - because its positive agendas conflict and destroy one another, as they rotate.
The modern Left is thus, over the long term, a means of wholesale destruction.
The Old Left (Marxists, Communists, Socialists) was essentially about promoting economic equality - and this took priority over everything else - including the abolition of poverty, which was done much better by 'Capitalism'.
But economic equality was (at first, anyway) sincerely-pursued by the Old Left - even when it led to economic collapse, famine, racism, sexism, and wholesale environmental destruction.
Post the mid-1960s the Left transformed into an ever-expanding 'rainbow coalition' of interest groups - feminists, assorted economically-unsuccessful minority races and ethnicities, environmentalists, Human Rights activists, promoters of first sexual liberation then inversion of traditional sexual values, criminals, illegal immigrants, the permanently-economically-dependent, and so on.
Thus the Left become democratically-overwhelming; while at the same time it became ideologically-incoherent - indeed utterly self-contradictory.
The actually-existing New Left is a loose grouping of asset-stripping interest groups, whose alliance is merely a tactical agreement to gang-up-on and exploit (or simply destroy) the diminishing minority of non-Left.
So the modern Left has no overall, cohesive, explicit strategy because all its claimed positive strategies cancel-out - its true underlying strategy is therefore implicit and denied.
Anyone who really cares about any one of the Left's supposed priorities - whether that be economic inequality, the sociopolitical situation of women, or of a particular race - can see that the New Left damages all of these groups in real terms.
The New Left actually, really, overall and significantly promotes inequality, damages the interests of women and racial minorities, damages the environment - over a timescale of decades, the Left damages everything for everybody.
All winners are temporary - today's winners (e.g. the Proletariat - the native male working class labourers) are tomorrow's demonized losers - in rotation.
Why is this not more obvious? Two words: the Mass Media - to which the population is ever-increasingly addicted, and which defines reality as whatever is expedient for Mass Media purposes.
The Left is misunderstood.
The New Left, the modern Left of Political Correctness, is not a conspiracy of Men, it is NOT about promoting the interests of any particular group - overall and in the long term.
The Politically Correct Left is NOT about pursuing equality, fighting sexism or racism, saving the environment or anything else positive - these are merely tactical excuses.
The long-term reality is that the Left is negative, destructive; wholesale, all-round, and strategically.
And this is impossible to human agency: strategic universal destructiveness is only attributable to non-human, purposive evil.
This is why there is a fundamental and ineradicable conflict - indeed there is a war - between Christianity and the Left.
Good people, even real Christians, may for various reasons find themselves fighting on the wrong side in this war; but that does not affect the fact that they are objectively fighting on the wrong side.
At this point in history, where we are now; a Christian Leftist or a Leftist Christian is an oxymoron.
In war, everyone necessarily fights on one side, or the other: God or Satan.
