I support gay marriage. I support gay marriage because I believe Conservatives support the institutions of commitment.

In this statement Osborne frames support for same-sex marriage in explicitly conservative terms. Rather than presenting it as a concession to liberal social change, he argues it aligns with a core conservative preference for stable institutions—marriage as a public commitment that encourages responsibility, fidelity, and social cohesion. The rhetoric attempts to reconcile a traditionally socially conservative party with evolving public attitudes by redefining “conservative” as pro-marriage rather than anti-gay. It also implicitly contrasts commitment and permanence with alternatives (informality, transience), suggesting that extending marriage strengthens, rather than dilutes, the institution.
