Brigada made a lot of enemies within our (unfortunately still substantial) neanderthal element with their anti-fascist stance and were effectively banned from attending Villa Park while Lerner was still in charge. A few of the lads still go to the games, just not as an organised group.
Always found B6 Project pretty cringy tbh, crowdfunding to get banners printed, it's always felt a bit plastic to me. Not sure why they've given up, but they only ever got a lukewarm reception from the fans in general IMO
