The short story from my previous work may show how liquid and sensitive the issue of discrimination is. I worked on behalf of NHS in the COVID-19 vaccination program. My main duty was to assign people to vaccination. At the beginning of the program, all consultants get a script and form that each singular person should be asked about gender. From my perspective, it was not appropriate to ask 89 years old person if this person is binary or non-binary, or transgender. Older people do not have a chance to pick a gender as we have right now. Of course, we can state that they have the same rights. They absolutely have, but if we ask this kind of question we distinguish them between people who had a chance to change sex with those individual whose age does not provide this chance. They have two options to be man or women sex was assigned with born. Those questions ask to seniors seem not to be nice or even intrusive or offensive. In meter of fact, they were. I shared my experiences about the issue with coordinators and the formula for dealing with seniors changed. Those kinds of questions were removed from the conversation script with seniors. This short story illustrates how plastic and flexible the issue of discrimination may be. And how sensitive and empathic staff should be to avoid discrimination. In this place, we must mention that language has its own limitation list of pronouns in language that stay unchangeable.
