Not doing any discrimination at all is a genuinely absurd position to hold. Discrimination is a necessary part of life without which society would collapse.
The question always is on which bases discrimination is good and on which bases it is bad. Discrimination based on race, ethnicity, gender, nationality, and other inherent characteristics of people is generally bad. Discrimination based on things like vaccination status is good.
Any human response that can be considered evil by simply who it is applied to…is an evil response all the time. People may justify that evil by their feeling they have the “correct” moral stance, but it’s still evil and shitty to the target group. Personally, I am not willing to participate in an intentional evil to any group even if I disagree with them r are different from them. If that makes me immoral, so be it.
