A lot of people are highly opinionated and keen to express how offended they are if anyone’s opinion goes contrary to their own. Some people even claim to have been personally injured or “attacked” by those who hold different opinions. Instead of just thinking “Okay, this is what I believe, and that’s what you believe, and both of these have merit even if we disagree,” people get incredibly attached to—and emotionally invested in—their ideology. They get defensive and aggressive if others disagree with their stance.
