While reading about boycotting science conferences in the US, it at first seemed empowering to take a stand. But more directly it feels like defeat to allow Republicans to “have” America like it was for the taking by any fool who came down the road. That said, there are vulnerable people who can be very badly hurt here and do need the comfort and safety of community. Maybe remaining outside the US is best for them?
For me, it makes sense to figure out a way to dis-enable the Trump project somehow. That sounds really presumptuous though.
