I feel like it's human nature to find an enemy by picking something that makes them different.

• someone from another tribe
• someone thinking jesus was a man and not a prophet
• someone wearing a red hat and not a blue one
• someone being a woman and not a man
• someone liking men and not women
• someone being from the east of a city and someone from the west
• someone being trans instead of male/female
• etc.

Eventually it'll be someone whose wearing cyber implants vs those who don't ala Deus Ex. It doesn't make it right but it just seems that we as a race need an enemy at all times.
