I do understand your frustration arguing the same points time and again, but truly we have been unable to come up with a solution. There are always new posters and new Lurkers and these are the ones being targeted by the re-assertions, repeat counter-arguments, etc.
Also, unhelpful behavior is not limited to one side. I've been on the receiving end of stinkbombs from both sides.
IMHO, it is best to leave such conduct unaddressed because it speaks more about the poster than the intended recipient - (more poison in the handle than the point).
You forgot to include the lies and false science ...
