Final answer:
The rights attached to marriage that are problematic for same-sex marriage in North America include legal protections and benefits that were limited to heterosexual couples and denied to same-sex couples.
Step-by-step explanation:
The rights attached to marriage that are problematic for same-sex marriage in North America include establishing legal protections and benefits for married couples that are not available to same-sex couples. For example, prior to the legalization of same-sex marriage, same-sex partners were denied visitation and decision-making power in hospitals, as well as the benefits granted to married couples in areas such as housing, inheritance, child custody, tax, and insurance. These rights and benefits were limited to heterosexual couples, creating inequality and discrimination against same-sex couples.
