On the other hand, I'd consider "deplatforming" as an appropriate term if and only if the action literally removes the platform used for expressing opinion and communication. E.g. If someone gets kicked off and kept out of some social media platform or gets denied the opportunity to speak at some public event, or interviewers boycott them even when their role normally would get interviewed, gets kicked out of a job which gives them public outreach (e.g. journalism or university) or some venue refuses to rent them facilities for a talk - to me, all of that is deplatforming no matter if it's because of political opinion or innate characteristics like the color of their skin or religion or whatever. If all the media agree to not show or discuss red-haired people, that's obviously deplatforming red-haired people. And on the opposite side, if someone gets hurt in other ways that don't change "the platform" - their landlord kicks them out, they get fired by an employer that "only" provides money but not a platform for outreach, their customers drop them - all of that isn't deplatforming but ordinary discrimination, again no matter if it's because of political opinion or innate characteristics like the color of their skin or religion or whatever (that would only affect whether that's prohibited discrimination).
