Why must Firefox and Opera fight?

Why must we fight?
Can't we at least just put it off until we distroy Internet Explorer?
Come on! Lets team up and distroy the true evil, instead of bickering all the time about which one is better...

It's just that the elitists like to hate on whatever is popular, like Firefox or Ipod. If Opera was the next big thing instead of FireFox they would be the first to scream bloody murder.
