Final answer:
The liberal ideology supports non-traditional, individualized marriage choices, including same-sex unions, while conservative ideology tends to uphold traditional marriage between a man and a woman. Over time, societal views on marriage have evolved with changes like the legalization of same-sex marriage reflecting a shift towards more inclusive attitudes.
Step-by-step explanation:
When discussing ideologies around marriage, the liberal viewpoint typically supports the idea of non-traditional unions, reflecting individual preference and autonomy. In contrast, conservative beliefs often support traditional marriage structures, such as those between a man and a woman, rooted in religious scripture and conventional family values. However, perspectives on marriage are dynamic and have evolved over time, allowing for greater acceptance of different marriage patterns including same-sex marriage, exemplified by the US Supreme Court's landmark decision in Obergefell v. Hodges which legalized same-sex marriage across the United States. Moreover, the existence of civil unions and diverse family forms acknowledges the changing social landscape and reflects the ongoing dialogue around what constitutes a marriage that is inclusive and non-discriminatory. These developments underscore a more progressive stance on marriage, attending to civil, social, and economic rights for all consenting adults.
