Come on man, there are Raider fans from all over, thousands of miles away from Oakland, we can't all go to the games. Sorry but it's a bullshit standard for determining who's a "real" Raider fan. I've spent the last 35 years flying the colors on both coasts and overseas and I've never wavered despite some of the worst losing periods in sports history. I bleed Silver and Black as much as you or anyone else.
That being said, I wish the Raiders had stayed in Oakland and I understand that you're losing something that's part of your life and important to you, yeah that sucks. I hope you have some cool final good times with your crew in that shitty stadium.
Out of curiosity, what do you plan on doing when the Raiders leave? Pick another team? Stop following football? Stay so drunk you're only marginally aware of what the hell's going on around you? Honestly curious, not judging.
