You can only be responsible for your own actions and no one can make you respond only you are responsible unless it can be proved diminished responsibility. So we are down to who wants to point the finger of responsibility and who reacted diminished.
Throw wine makes you a (last leg) dick. Throw an actual glass back makes you (last leg) bigger dick. Pick up a chair makes you (last leg) dick of the night. Going on social media and saying your actions were part of a BB pantomime makes you (last leg) dick of dicks for not taking the responsibility for your own actions..... which you knowingly would prompt a reaction in the first place.
Finally, those producers who knowingly employed and aired someone on live air who's social media stated they would like to throw wine in the face of a contestant for insulting a friend make them (last leg) total dicks for allowing the stage for it to happen.
Who's the dick you decide.......
