It’s fascinating that people still see these things as new or unique to our current administration. This has been an issue for decades that were often ignored or minimized because it only affected smaller more marginalized groups of people. For example conferences involving HIV/AIDS had to contend with these issues for decades due to the blanket ban on HIV+ individuals from entering the country, even for a scientific conference. Often the conferences would continue leading to schisms in the communities and competing conferences that would ultimately disagree on fundamental principles in science and policy.
