Do Baltimore fans generally root for DC NBA, MLS and NHL teams (leagues they are not represented in as a city, and because they are close by) or do they hate everything DC?
Baltimore sports fans generally like DC teams for sports they don’t have with the Caps being a clear favorite. During the national anthem at home games you’ll hear the crowd scream “O” during the “O say does...” section in tribute to the O’s (Orioles).
There’s really not a lot of hate on either side. Some die hards hate the Redskins / Nats and vice versa but it’s generally pretty cordial and it’s mostly a friendly rivalry. It helps that in the NFL and MLB they’re in different conferences. I grew up in a Baltimore suburb but am DC sports through and through; I grew up with friends that are Ravens/Orioles fans and friends that are Redskins/Nats fans. Mostly just friendly shit talking.
I think another thing that helps bond DC and Baltimore with regards to hockey is the hatred for Pittsburgh. Ravens fans hate the Steelers. No explanation necessary for Caps/Pens. A common enemy between both cities.
