This is not the work of a pathological hater, it would appear to be the work of an agent provocateur. Quite simply to attempt to engage at others on an emotional level. This has all the hallmarks of communications disinformation type strategy by someone employed to do a job. The job is to antagonist, disrupt, discredit, spoil, and above all provoke emotional outbursts from others. In short, to deliberately "get your goat". Further, these emotional responses appear to be to be elicited for the benefit of non-pilots & press (and they do) who may be watching this thread.
Notice the complete lack of emotional commitment to any cause in their posts. This appears to someone employed to do a job, and they are just doing their job. Why would someone go to such a length to investigate the minutiae of contracts for hate on an anonymous BB? Way too much research has been done by the individual who just hates. More likely, the research has been handed to them by their superior.
Any fact or argument will be taken, altered & used against you. There is no attempt at rational or logical debate. Any argument or fact will be twisted to attempt to provoke an emotional response.
I visit a lot of other forums with much more highly skilled professional disinfo operatives. There is nothing subtle, nuanced or clever about your work, you lack any degree of subtly, plausibility, credibility, knowledge or authority. They are the tools of professionals, you are straight out of amateur hour.
