Antifa thrives on anonymity. They don't like it when society knows who they are. This is why they wear all black, had progressives lobby the state to prohibit the release of mugshots and also why they absolutely hate Andy Ngo.I don't know what's driving them, could be many different angles. If you look at Antifa they thrive on confrontation but fact is that attrition will lessen their numbers as there are not many of them. More like high school groups that have their own click.
Its amusing they go out of their way to dox others but when it is used on them they throw temper tantrums.
