Mahatma Gandhis methods for converting an opponent
Conversion is the process by which an opponent comes around to embrace your objectives.
1 Refrain from violence and hostility.
2 Attempt to obtain your opponents trust through
...~ Openness about intentions
...~ Chivalry (kindness if the other side experiences an unrelated difficulty)
...~ Making behavior inoffensive without compromising the issue at hand
3 Refrain from humiliating an opponent.
4 Make visible sacrifices for ones cause.
...Ideally, make the suffering of the aggrieved visible.
5 Carry on constructive work. Address parts of the problem you can address.
...Make improvements where you can. Participate in activities regarded by
...everyone as benefitting everyone.
6 Maintain contact with the opponent.
...This is absolutely necessary if conversion is to succeed.
7 Demonstrate trust in the opponent.
8 Develop empathy, good will and patience toward the opponent.
This is the best you can do from your end. External conditions may still prevent conversion.
