Sunday night marked a milestone for gay rights, as Robbie Rogers made his debut with the L.A. Galaxy, becoming the first recognized openly gay athlete in a major American sport. Earlier in the day, however, Minnesota Vikings star Adrian Peterson reminded everyone that tolerance is not necessarily the same thing as acceptance.

Speaking to Bruce Murray and Amani Toomer on Sirius/XM NFL Radio, Peterson made it clear that he is not a proponent of gay marriage. Peterson said he has gay family members and is tolerant of gay people, but he doesn’t condone gay marriage.
