It already is a thing. And many are pointing out that the color scheme works very well with being called Commie.
“Commies” isn’t the worst nickname opposing fans could come up with. People call the Giants “G-Men”, after all…
The Raiders have a piratey-looking logo I guess, but you never heard anyone call pirates “Raiders.” Pirates are either pirates or buccaneers.
Fun fact; when the team was founded, they had a name-the-team contest and the winning suggestion was “Oakland Senors.” (Add a tilde above the N; I don’t know how to type that.) They decided to, well, overrule the fan vote.
It is supposed to be a pirate, and was modeled after actor Randolph Scott.
When the original contest was run, it was announced that the winning name was “Senors”. There was a lot of skepticism about that, though; the owner at the time, Chet Soda, was fond of calling people “senor”, and the name was heavily derided. The name actually was established as Senors originally. But only for 9 days, then it was changed to the third choice which was Raiders.
Speculation at the time was that the contest winners was rigged, and Soda picked the name himself. None of that is verified, but it seems awfully suspicious. Soda claimed that his first choice would have been “Mavericks”, but who knows if he was just covering or if that’s the truth.
Here are some other names considered:
Admirals, Lakers, Diablos, Seawolves, Gauchos, Nuggets, Dons, Costers, Grandees, Sequoias, Missiles, Knights, Redwoods, Clippers, Jets and Dolphins.
What, no “Bad Hombres”?
Honestly the name “Oakland Hombres” sounds awesome to me. 
Really catchy and alliterative.
Indeed.
And they could honestly claim to be men. Real manly men. Men in Tights, even!
They run around the sideline looking for fights!
(Actually, that was their reputation for a while.)
Lakers? Seriously? Also, WTF is a coster.
A costermonger, coster, or costard is a street seller of fruit and vegetables in British towns.
I mean, what’s more intimidating than this?
