Where did you try to donate that banned you? At least on the American Red Cross site it seems transgender and nonbinary individuals are not banned from donating on the basis of their non-cisgender identity, but I know not everyone is American and perhaps some donor centers even in America might be more bigoted about things. I am sorry you experienced this.
Your body, your choice. But I’m not really sure how the administration being awful means you don’t want to donate, unless you are worried of grievous bodily harm being done to you and then you would want all your blood.
