Sqad - they are human beings, no dispute there.
But by the fact that Prescott becomes, through choice, an elected politician and government minister, that means that some of life's little luxuries, like brawling in the street, are no longer an option for him because, due to his status and (considerable) remuneration from the public purse, the public is entitled to expect him to behave with a degree of personal dignity, as well as ensuring he does not flout the common laws of the land which are made and enforced by the government of which he is a senior member.
So if you want to be a incoherent womanising braggart who fights in the street - go ahead, but not on the public's salary in a position as a government minister - it is not accetptable.
