In the aftermath of Vatican II, opponents of the radical deconstruction of the Church (what Pope Paul VI, soon to be 'Blessed', called its 'autodemolition'), had to decide on a strategy. Since this was not going to be a purely negative strategy of attacking something from all and any side, like the radical liberal strategy, it was going to require serious thought and difficult judgments.

(As an aside, conservatives are perfectly capable of allying with others when a purely negative objective is in view. Explaining his alliance with Stalin, Winston Churchill said: 'If Hitler had invaded Hell, I would at least have made a favourable reference to the Devil in the House of Commons.')

The people we call 'neo-conservatives' decided to accept the reformed liturgy, give the best interpretation possible to everything coming out of Rome, and to rally round those aspects of doctrine which were being most vigorously upheld in the Papal Magisterium, which were issues of sexual morality and abortion. Pope Paul VI issued Humanae Vitae condemning contraception; St John Paul II turned out to have even more to say on this, and on abortion as well; Pope Benedict XVI also had a very clear track-record on these issues.

The key to the unity of the liberals and leftists is that their immediate aims are negative: they aim at destruction. The common ideological thread is that traditional structures, whether economic or social or doctrinal and liturgical, are oppressive and stop people from flourishing. They unite to destroy these things. Since they can be undermined and destroyed from many angles, having different groups working at it from idiosyncratic perspectives is a positive advantage. Radical feminists want to destroy marriage because they see the family as a patriarchal power-structure; homosexual activists want to destroy marriage because they want their own relationships to be accorded equal status as married relationships. These two groups do not agree about anything apart from the importance of destroying marriage, and they attack marriage with completely different arguments. The incoherence of the overall attack doesn't matter; it serves only to make the anti-marriage coalition appear all the more comprehensive.

This isn't a bad moment to reflect on something which is often said: while liberals support each other in their efforts, conservatives often don't, and lose out that way. Peter Kwasniewski mentioned it today, in an aside. Speaking of Bugnini and his colleagues, he writes:

They were men who seized their opportunities and did not sit on their hands wondering when other people would do the job for them, or worse, waste their time on endless bickering and hairsplitting. Like our political liberals, they could lay aside small differences for the sake of gaining major objectives.

My question is: why is it so often the case that liberals and leftists are able to present a united front and their conservative opponents cannot? And can it be remedied?
