Yes, and we should stop having discussions about abortion, gun control, and the environment because we've already heard all the arguments for and against, right? Just because you lost interest doesn't mean that the topic isn't deserving of further consideration.
Just like no scientist gathers up all the information in their field and says "We've been doing this for a long while, we're through now", neither should anyone feel that they need to refrain from voicing legitimate grievances because you've become so lazy and inept you no longer feel like hearing them. You're a mad little despot of a hill made of beans, claiming to be Lord of all things fandom. I did not kneel at your inauguration and I do not heed your foolhardy proclamations now.
You, "Bob", are the disease in all geek culture. The one that rants and raves in a little tantrum of your own twisted whims, and when you are brought to task you sulk because the world does not see you in the prism you've grown in your mind's eye. You're a Batman villain, all frills and fancy words describing the truth of the world as you so clearly see it, all the while your true home is a padded room where they can try to cure you of your delirium.
As much as it hurts me to say it, you're the escapist's front line nerd. They need you in the trenches fighting the good fight, and not sitting on the sideline lamenting how fruitless the argument is. Get off your hill, close down Wikipedia, and get back into the fight. You can rest when the Escapist replaces you with someone competent.
