First of, ACAB. There's no denying that American police are steeped in institutionalized racism and violence.
But secondly, I'd like to point out that conservatives will never view men's mental health as a real issue (cops are disproportionately male), and liberals will never view cops as human enough to have mental health issues.
The United States is the country with highest rates of civilian gun ownership in the world. Every police encounter has an inherently higher risk of gun violence. Now, cops frequently provoke when they should deescalate. But multiple things can be true at the same time. Policing as a profession attracts narcissists and sociopath, policing as an institution enables that behavior, and policing in a country with rampant gun ownership is a highly stressful and traumatic experience.
I say this as a survivor of a mass shooting. Gun violence changes how you look at your environment and the people in it. There is no room and no person that escapes your unease and suspicion. I can only imagine what a work environment that perpetually affirms those suspicions could do to one's mental health.
None of this excuses police brutality. I just think that we need to start looking at cops as legitimately mentally ill people, whether they are sociopathic or traumatized.
Destigmatizing men's mental health means every man's mental health, and the left's inability to address this blind spot is allowing the manosphere to dress its alpha male bullshit in police and paramilitary aesthetics.
What about people who can't donate blood, or can't do so without great inconvenience? Where do you draw the line for moral responsibility?
What about people who have a phobia of needles, suffered from medical abuse, or have adverse reactions to donating blood that makes them sick for a few days or weeks?
If we are talking about people who contribute to other's health through their own bodies, does that mean every mother is at the top of the list because birthing a baby is a contribution to another's health?
What about medical workers working 12hr shifts and completely wrecking their own bodies in the process? Is that a lesser contribution than someone who donates blood once a month? To go further, where would you put a factory worker with repetitive strain injury who makes the medical equipment that is essential to treating others?
If we want to allot the use of blood based on one's contribution of their bodies, we have to first ask what it means to contribute. No donor lives in a vacuum. If you can donate blood, it means you are supported by circumstances that leave you in good enough health to donate blood.
