It is not reasonable to make some serious claim somebody is lying when anybody living in the real world can see he said it as a joke
Sadly the joke flew a mile over your head
There are many lies told in this forum, later claimed to be a joke, irony, or sarcasm, but not until challenged.
Sadly, some people believe the jokes as reality.
Additionally, it is important, especially in these forums, to highlight to some, that their fake news is not true. They may even believe it themselves.
Until they accept that their fake news is a lie, they continue, or even in some cases. yours especially, they still to continue to express lies, knowing full well that it is a lie.
Especially in vinty's case, some of what he says is dangerously distorting reality.
Someone else in this forum is also well known for distorting things.
