It's not ridiculous. There is a whole phenomenon where players behave differently in online games depending on the personality and social expectations others will have of the character they are playing as. If your character is expected to be a dick players act more like a dick, whereas if your character is expected to be nice players act more nicely. This occurs with the same players playing on different characters. This is called the "Proteus Effect" if you want to look into it more deeply.

Given that occurs I don't find it difficult to think that people would get into the role and atmosphere even more when doing it in VR.
