Since this is apparently a space specifically for contention, can I challenge the entire premise of this thread? ^^
I don't really see how it's particularly useful for 'training'...it's not as if only pointless topics of disagreement are allowed (and honestly, if that were the case, it'd be even less useful).
And is there really such a thing as disagreeing "without bad consequences"? What do you consider a "bad consequence" of an online disagreement?? The fact that someone might think less of you? They can still totally do that here or anywhere...that's not a thing that's under anyone's control.
The fact that they might call you names and mock you? To be honest, I think 90% of the users on this forum are more respectful than that; if they're polite on this topic I don't think it's because they're "challenging" themselves in self-restraint. They're probably just being their normal level of civil...
I guess what I'm saying is that this is kind of like "preaching to the choir"? Most of the people who will respond don't actually need this kind of practice, and those who do need it either won't be here or will probably just ignore the rules once they feel strongly enough about something. =/
...Anyway just to play along, here are some opinions of mine:
- Most people in the U.S. aren't actually afraid of clowns, they just act like they are because it's trendy.
- Art school is pointless unless you're looking to make connections, and even that probably isn't worth the cost.
- You should never take art advice verbatim. There ARE exceptions to every rule, and understanding them is just as important as understanding the rules, if not more.
- I'd say 60% of everything you learn in school is unnecessary. Nothing against school though: I don't think necessity is the point. Exposure is the point, and thus I think school curricula should be a LOT more flexible, ideally.
