If the page does not show correctly, most people send an email to the 
page author, or ignore it.

I doubt that many people will surf the web, come upon a single page that 
isn't working and make an assumption that the browser is broken. 
Typically, it requires many such pages for people to make that assumption.

We have to operate under the assumption that most people act reasonably. 
We can't make all of our decisions based on unreasonable behavior. If we 
do this, we should stop anything to do with CSS, SVG, Canvas, Script, 
HTML, and so on, because all of it can be used incorrectly, and people 
act unreasonably or even irrationally because of it.
