No matter how many times you swear you will not have this debate again, somehow you get pulled back in and find yourself taking a stand. Whether it's Android vs. iPhone, or Marvel vs. DC, you just can't stop! What's your greatest weakness when it comes to geeky arguments?
Tell us in comments which issues are sure to make you start arguing, even when you are just trying to have a nice, peaceful day with no giant expository rants about the meaning of science in Doctor Who (for example). Also, please just DESCRIBE the debate, don't start one!
