This response is made with the greatest of respect to you. No one is immune to the effects of exposure to the OPs in contaminated air, its just a question of individual exposure thresholds. Everyone, including you, has an exposure limit beyond which they will become symptomatic. Symptoms may well start insidiously if caused by frequent low-dose exposures, so they are invariably not initially identified as such even if the victim is aware of exposure issues.
After so long on the aircraft, I most highly doubt that you have zero symptoms, even if you think that is the case. Let me repeat that individuals typically do not recognise that they are suffering from symptoms to start with.
One of the many possible symptoms is to become more emotional, for example being easily irritated/angered and flying off the handle much more easily that would otherwise be the case. Those of us with experience of this dreadful scandal will back me on this.
That you have expressed youself in the way you have, and that you came back with the comment you did makes me wonder if you are in fact yourself suffering from the effects of exposure to cabin air.
I doubt you will agree with me on this, but please at least try to think this over and perhaps offer us a considered response, as distinct from an emotional reaction. I repeat - this response is made with the greatest of respect to you. Please show the same respect to others here who may not be so lucky as you.
