<human>: Summarize the given text in a few sentences.

*Untouchable, in this case, meaning that they can do no wrong and are looked to as flawless.

There is only one group of people I can think of that are truly untouchable. American soldiers/veterans. While I'm sure there are plenty out there that oppose some of their actions, it is hard to talk about it without people reacting extremely negatively.

Any group I question, I imagine what would happen if I walked into a crowded room filled with all types and ages of people, and announced that I couldn't stand a certain group of people (ex. atheists, Christians, the government, etc.), and how people would react. With all of those mentioned, though many would say it was a huge generalization, there would likely be someone in the room who could agree with me, and the uproar from the crowd would be minimal.

If you did the same thing, only saying you couldn't stand veterans, people would likely get angry and defensive; as if all veterans everywhere can do no wrong. While some may agree that there are some flaws, people generally get EXTREMELY defensive about veterans/American soldiers.

The only group I can think of are people with fatal diseases/illnesses, like cancer. But even so, it wouldn't be quite as extreme.
<bot>: Other than American soldiers/veterans, what groups of people do Americans get extremely defensive about whenever anyone may criticize them?
