Love: It’s one of the most powerful forces on Earth, if not the most powerful. The number of songs that have been written about it is too high to count and there’s no shortage of films about two people finding that magical spark between them. But it seems that the love a person has for their local football team might outweigh the love they have for another person.

Fanatics released a list of which teams’ fans are the least likely to date fans of a rival team and Ravens fans came in first, with 50 percent of fans surveyed saying that they would not date fans of the Pittsburgh Steelers.

Coming in behind Ravens fans are Bears fans, with 45.7 percent of fans surveyed saying that they would not date a Packers fan.

The Bears-Packers rivalry spans 194 games over 97 seasons, giving it the longevity. But the Ravens-Steelers rivalry has bred more hostility between the two teams, despite the fact that they have only faced off 46 times over 21 seasons. That’s fairly remarkable.

Ravens fans make the list a second time, coming in at the number five spot. This time it’s 42 percent of fans saying that they would not date someone that is a fan of the New England Patriots. Ravens fans hate Patriots fans more than the fans of the other AFC East teams do, as only 33 percent of Buffalo Bills fans said that they wouldn’t date a fan of the Patriots and the Jets and Dolphins fans didn’t even make the top ten.

Fanatics also released a slightly NSFW list that shows how much fans of one team despise rival fans. Ravens fans also made the top of that list by a pretty wide margin.

There are plenty of metrics that are used to determine how rabid a particular teams’ fans are. Some look at ticket sales, others look at the suffering fans put in towards a team that has been awful for decades. But Ravens fans truly hate their rivals more than anyone else to a degree that might be unhealthy.
