>That's always happened, but it seems to have become much more common.

That seems like one of those things that has always been extremely common, but is difficult to see when reading history rather than news. People always justify their own thoughts and goals over trying to understand another point of view.

Yes, but I think the differences in the ability to disseminate criticism to a large audience over time have have changed how this affects society. That is, people have always done this, and probably always done it about the same amount, but haven't always had it visible to hundreds, thousands or millions of others as easily as it is now. That's not really what I said before, but I think better encapsulates what I mean (or, at least, what I mean now that you've forced me to think about it a bit deeper ;)

I understand that reaching billions of people seems scarier, but how does it really differ from being able to convince the entire Roman Senate with one skilled oration? Convincing either group could lead to horrendous acts being committed.

The main difference is that there are more people, they can interact more, and their opinions matter slightly more than in the past. Those things also allow us to understand the deeper motives and purposes far better than ever before, even if we still foolishly ignore them.
