Too right they should be. As long as it’s not random abuse, I’d prefer to be sat with passionate fans than the corporate types. The atmosphere at Twickenham has sunk in my view, from what I’ve seen anyway. Expensive tickets prices a lot of genuine fans out so what you have now are probably fairly affluent/well to do types who are going to be less boisterous/passionate. This may be a bit of a stereotype though.. but ultimately the audience that’s affordable for twickenham now, is pretty much the leading factor for the lack of atmosphere (along with playing terrible rugby for years)
