Because it's not analogous to the op case, for one. And two. you're conflating a trans person with nazis and the KKK. It's disgusting.
Alright, I'm going with you don't comprehend this.
You don't seem to have comprehended the reasoning for the statement.
In context it is about why the features of being a Nazi are not the same as the features of being trans and so these features play a role in decision-making vis-a-vis so-called discrimination. Since some people come up with various OTHER reasons for treatment of Nazis differently based on their OTHER features, they are not concluding things for the same reasons across the board in the two different cases. Ergo, one can infer you are CONFLATING the different treatment-associated features of being a Nazi with a single treatment-associated feature of being trans.
Since you have not yet comprehended this, as an exercise to increase your understanding, I will ask you not to jump to your first instinct emotionally and try to argue with the above. Instead, please just use the example of
al Qaeda instead of Nazis. See how far you can take the analogy and why eventually you will agree after several scores of pages why it is a bad idea to have made the analogy.
