This is a very emotion-based response to a rational post. I understand you are in the profession and it is important to you, but that shouldn't mean
> This is a terrible idea for so many reasons
So list some of the reasons, rather than just dismiss the idea.
> I am a first responder and I would gladly carry insurance if I was compensated for it.
So now it sounds like it isn't a terrible idea at all and you agree with it if compensated. The take away I get from this is "first responders are paid too little to be held responsible for their actions." Lots of professions are paid very little and are still held responsible for intentionally reckless or malicious behavior.
> I would now like to be compensated for the exposure to disease, injury, environmental toxins, and more.
Sure that's fine as well, but against has no bearing on a person being responsible for their actions. Again it sounds like a justification of "first responders don't have to be responsible for their actions because xyz other concern". And shouldn't your union be negotiating for compensation for these things?
To me it sounds like exactly a viable solution. First responders must carry insurance for extremely negligent or malicious behavior, and should have an increase in salary across the board to cover average insurance cost.
