Anyone who doesn't occassionally sincerely ask themselves the questions, "how might I be wrong?", "what might my own biases be blinding me to?," and, of course, "am I a bad person?" Is not only ignorant, but is indeed a bad person because they're not willing to reflect on how their willful ignorance is hurting both themselves and those around them.

Learning to be uncomfortable with your own beliefs and wrestling and coming to terms with them, and, most importantly, changing your point of view over time with the aim of increasing your empathy for others not like you, is part of what it means to be an adult. There are very few adults in this world.
