People that pull their strongest cards for emotional appeal on a subject almost instantly. Things like "that is so offensive" and "you're (or they) are the lowest of the low" and so on. This is often done on a touchy subject but not the extremes of that subject. For example, hitting a child, war crimes, racism, etc.. With the kind of offended and patronizing or hateful words chosen you would think the topic was about 'A Child Called It," impaling people by the hundreds to line a castle, chemical weapons and slavery vs. the reality of it being a fraction as bad. If the subject isn't to the extreme, it's a good way to get eyes rolled at you if you start off with screaming foul with a clenched fist as you type with tears in your eyes.
What happened to subtlety, working your way into a main point where you can really drive the pathos hammer hard for an ultimate and much more effective point? If you waste all your ammunition right away you end up just repeating yourself over and over again when you've already been brushed off from the start because you've shown you can't try to understand or look at something a little more objectively. It also makes for extremely poor debate/dialogue about such subjects.
