Eh, both statements are true.
- your ultras are laughable/non-existent, surely you will agree (therefore that lone Dortmund fan holding up his scarf in front of your fans is not really "brave")
- your fans overwhelming Barca audience really is shameful to those Barca fans as your lot is pretty quite for Bundesliga standards and your stadium is known to be as quite as aelementarycemetery at times, especially if your teams is losing (see Arsenal game).
do you see me or any other bayern gaf member complaining about your ultras? I agree we have ridiculous ultras but you have one of the worst ultras in the league too. sure they're loud but many of them are homophobic or even nazis. you can't deny this.
our fans were great against juve in both games for example.
