I do not try to hide it -- see other comments. I have no problems saying that I am an aircraft instrumentation engineer, nor am I under any obligations to hide that fact. I got that feeling because it seemed as if you might have been trying to say that my affiliation with the industry made anything I say suspect. Not all of us are shills, or have some ulterior motives. I just have knowledge of what's being discussed, and I wanted to share it. What could have been malicious? I didn't know. Probably nothing. These are emotional responses I had, they do not have rational bases. I have no idea what you were trying to achieve, to be honest. But you have addressed that you meant nothing personal, and I accept this.
