it is already quite annoying that you so often introduce topics here that are seemingly barely relevant. But this kind of email and language is in my opinion out of line on a whole different level, and I would appreciate it if you could leave your (in this case, categorical) personal attacks and snidy remarks away. Not only are they totally irrelevant and do they not match reality at all, but they don't help your case either. 

If there is any reason why people are ignoring you (and I have certainly that tendency nowadays), you should search the reason for that in the language of your emails, and the topics you bring up, rather than assume this is a general problem.
