You're idea box. It is not wrong to disagree, but as I have said before, it is wrong to insult. I assume in High-School you learned how to argue in an essay? Defending and attacking a certain idea, cause, person, etc. is fine, but showing them respect is valuable to your ethos. Calling someone's ideas stupid is not the right way to go. You and Esau seem to have the arguements against her down, but the disrespectful terminology (i.e. stupid) is wrong. This is often a symptom of someone's inabillity to step in another person's shoes (however briefly). If that is not the case with you then I am sorry. As to the debate, although Serious Discussion has been a good place to hold debates, that is not necessarily what it is meant for. Many people come here to learn about others without knowing that fierce debate is imminent if they state an opinion that is disagreed with. I first came here for that reason, myself, and it sounds like eclipse did, too. To be honest, I think a "Serious Debate" forum would be a good addition to this site. Discussions could start here and when they grow heated, move to the debate area, allowing casual players to just hang out and also satisfy the firey combatants such as yourself.
EDIT: At your EDIT-You are right about the "crappy defense" thing being worse than no defense, but who judges what is reasonable? Let me make this clear first: I do not agree with her. Nevertheless, just because something seems a certain way in your eyes does not make it true, nor does it make it false. So, really, I'm arguing that there is no point to arguing. How utterly silly of me.
