If you can have at least one friendly interaction with a member of the “other” group, you’ll find it far easier to listen to what they’re saying, and maybe even see a controversial issue in a new light. You may not agree, but you’ll probably shift from Manichaean disagreement to a more respectful and constructive yin-yang disagreement.
