Its actually not hard for us to deal with. As a matter of fact, you seem to be the only person who is belly aching about trophy droughts and selling players. Sure, you see a lot of plastic fans who jump on bandwagons and want tons of money spent every year, and when they don't get their way, they suddenly switch their allegiance to the new stylish team, be it Dortmund, City, or Barcelona.
Real fans like aygov & myself understand when & why a player needs to be sold. We never claimed Arsenal have some great dynasty that they must uphold. Sure, we want them to compete for titles every year, but with their methodology of buying & selling players, a lot of things have to come together to win in the hardest league in Europe with 3+ teams who spend twice what we do every transfer window. When those things don't come together, yes its a shame, but we still love the team & enjoy getting to see them playing in European competitions against the worlds best every single year.
I can understand why you don't grasp the concept of selling players, after all, you support a team who offered way too much money to Grant Holt, who should have been sold when he turned in a transfer request at the age of 31, but instead has turned out to be a dud. Actually, by your standards, if Arsenal are full of "scrubs", I'm not sure what you would classify Grant Holt as.
