I’ve seen this type of tactic really well displayed in this video by SquidTips.
This man talked to a fucking Proud Boy wearing a rainbow shirt that said in large letters “GAY” on it with a button that had the hammer and sickle in trans colors, mentioned his partner was trans, and got the guy to agree with him on the fact that he should be focusing on the class war rather than the culture war.
Even Proud Boys and people on the far, far right still think that what they’re doing is good for society. You don’t have to convince them to “stop being evil, switch to being good” you just have to convince them that “this is a more effective method at making society better than what you currently believe is the best.”
Will it work for everyone? Of course not. Some people are just going to be too far gone for you to reach, but there’s a lot more people than you might think that could be swayed, despite what the flood of media coverage of the extremes of society can make you believe.
Fair enough, though I do think this can still help with any broader approach to changing their overall mentality.
A moment of consensus on its own might not be enough to sway someone, but if they hear someone try and contradict what they had recently agreed on, it can then make them feel more cognitive dissonance, and potentially make them at the bare minimum just stop and think for a second.
If someone else is later trying to sway them in some way, it’s going to be easier when that person says something, and they can think “I remember saying something similar” rather than “this is the opposite of what I already believe.”
Plus, there’s also just the sort of “exposure therapy” factor to it, as well. A lot of people are radicalized to believe that the “opposing side” is pure, limitless evil, and that they hate you and want you dead, so just interacting with them can be enough to help slowly deradicalize them.
For example, this Pew Research article states, regarding the likelihood of people to support trans people’s existence:
But of course, that isn’t just limited to acceptance of people by gender. It also applies to race, social and economic status, recipients and non-recipients of welfare programs, people working in different industries, etc.
Again, not saying it’s at all some magic universal way to change someone’s mind, or that on its own it’s necessarily a factor that can override their overarching condition, (hell, that quote from before shows that it had a much smaller impact on republicans than democrats even given the same exposure) but the more and more this happens, the stronger and stronger an effect it has overall, and I’d say that alone makes it worth doing.
