The San Francisco 49ers were the first NFL organization to tweet their support of the United States Supreme Court's landmark decision to rule same-sex marriage a legal right in all 50 states.

The 49ers organization has been vocal of equal rights during the past decade, participating in the "It Gets Better" campaign in 2013, urging young people struggling with their sexuality to seek help.
