I care about explaining where I'm coming from on this subject, so that reactions like "you're an hater" or "you're anti-Cyclops" are dismissed for what they are: shallow arguing, easy cop out and ad hominem.
Yeah.
Someone.
Someone as opposed to everyone/a lot of people.
Thus the need to nuance, thus the reflex of pointing at the rampant generalization done at times, because "it's simpler".
And yes, there are exaggerations being made at times, like when I read stuff such as Avengers=fascist scum.
No, it would completely depend on the writer willingness to make it work.
IRL, trials becoming tribunes for the individuals to express a philosophy or get across a message do happen.
Just a few weeks ago here in France, there was this doctor's trial where the man pushed for a reflexion on euthanasia (he was accused of having aided some patients to end their lives prematurily).
It caused a national debate on the subject, up to a point the government had to take a stance about this.
And that's just a recent example I witnessed, there's no reason why in a work of fiction this kind of things couldn't be transposed and happen.
