Some people go through their life without the blessing of being able to understand jokes. In cases like this, even sarcasm is a big no.
So, the only good and real advice would be to avoid wasting your time trying to polish all things up for them. In the end, you can be sure that they won't even try to get the image of what you mean to say.
The Internet trolls are going to keep trolling, and all these people will keep feeding their egos and living in an illusion about themselves.
