If you type one thing and expect people to understand that you meant something else then I will have to assume that by this:

>>people who do post grads tend to be well rounded enough to have read a bit of philosophy, or at least, they did in my day.

You can complain that people on the internet misunderstand on purpose (and I agree it is far to common), but that complaint is only valid if you communicate clearly yourself.
