Free speech means that people can say everything they want until they damage the physical integrity of respective person.
You're putting a restriction on Free Speech that doesn't exist on this forum. There are restrictions here ("doxing", "off topic" and "spamming" for example). But damaging the physical integrity is not one of them.
If you want to be an obnoxious person than you're free to do so. The topic of this discussion is "How offensive can a post be". I think that question has been answered. What do you actually want from this thread?
Btw i dont need to try to discredit you ...
... everyone with half a brain can see that you are one of the dumb penny sig spammers.
You are not even half as smart as you think you are.
Wait, what?
And yes scientific research is agreeing with me.
A quick lookup shows there have indeed been some studies that suggest an hereditary component to lying. However the consensus is still that lying is a behavioral study. In short, science is not agreeing with you.
