I'd debate saying those types of supporters have always been there, only now social media has given them a platform to get together and have a voice.
Once enough idiots get together and reaffirm their beliefs in this echochamber, ie Twitter and to a point this board, they think their opinion is actually more valid than every other supporter simply because they are making more noise and more posts.
Social media is a great way to connect with people, the unfortunate downside is a lot of people are f***ing idiots and once they band together, things get nasty. Especially when it comes to football and Sunderland.
Yep, there were plenty of wankers at Roker Park as well.
