Much like other asymmetric relationships (such as therapist and client), there are complications related to power dynamics that can arise with any NVC trainer having sex with a participant. For one, there's (counter)transference. And there's potential for things that may not move outside this asymmetric relationship -- such as projections where the participant, and/or the trainer, is guided by un-healed pain of their "inner child".
There are many polarizing issues we can resist and fight over. The word "resistance" can mean fighting against what we don’t agree with in counterproductive ways. It can also be the illusion and futility of mentally fighting against reality of 'what is'. But acceptance, non-resistance, of what is doesn’t mean powerless resignation. Another way to resist is to accept and love whole-heartedly, with empathy and care for the people doing the things we are resisting.
