But for Labour and many self-styled “centrists”, all of this is too much to consider. We have now had a generation or more in which they have made it imperative to remove “stigma” around people’s choices in terms of sex and relationships, especially if those choices are associated with ethnicity or race. That one of Britain’s largest ethnic minorities has been found to engage in a custom which, notwithstanding the medical consequences, is inherently revolting to most English people, is more than they can bear. For them, the entire subject is simply racist, let alone any specific opinions or policies one may come up with about it. They want it to go away, and the easiest way to do that is to stick firmly to the liberal line that whom people marry and have children with is their own business.As a result, cousin marriage is now in the same drawer as questions such as the wearing of the niqab, which divide liberal opinion between those who emphasise the autonomy of minority communities and those who place primacy on the individual. This is mainly a debate going on among people who consider themselves “progressive” in one manner or another. As such, their arguments tend to be couched in the language and assumptions of the Left. Many conservatives and populists are naturally in favour of banning what they regard as a backward foreign practice as a matter of principle, but they are happy to amplify arguments for doing so on grounds that sound more enlightened and humanistic if others are already articulating them.
So we begin to see the argument that cousin marriage is a patriarchal imposition on the autonomy of individual women of Pakistani heritage, forcing them into marrying cousins with the risk of giving birth to unhealthy babies. Surely, they reason, no woman could possibly want that for herself, or for her potential children. It is a coercive practice, designed to shore up the power of the male elders of clans, by marrying their own offspring together. This is an argument which many progressives, especially male ones, know they have to treat far more cautiously than those from the Right which can be dismissed as racist or stigmatising. Especially since any perceived disregard for the specific rights of women from “marginalised” cultures risks making them look like the racist ones. This followed on from the public debate around the niqab earlier this year, in which nominally left-leaning or liberal feminists seemed to make the argument more stridently and confidently than they had done previously; that full face veiling was patriarchal and oppressive, and that a secular society had a duty to intervene. Unlike their counterparts in other English-speaking countries, the success of British feminists in halting and reversing the tide of gender ideology has clearly made many of them far less patient of other parts of any so-called progressive coalition insofar as they might infringe on the freedom and autonomy of women — and a bloody good show too.
