Callistemon, in regard to your post @ 16:02 today, the video you use to demonstrate "fights are common" in Parliaments worldwide is made up of countries that in the main have only obtained a democratic system in recent years and therefore no long experience in that as the British Parliament has.
South Africa, Spain, Japan were three of the countries featured, and all have escaped from the yoke of extream right-wing regimes in the not too distant past, while another country featured only emerged as a nation on the collapse of the Soviet Union.
Therefore in the light of the number of Parliaments there are in existence worldwide, and the relatively short history those displayed have, I believe that the UK Parliament remains in "a poor light" for its behaviour between members of the House of Commons.
Further In the above, many see the British Parliament as the "Mother of Democracy." Therefore this country should be setting an example of how reasoned debate can be carried out under a democratic system but sadly that has not been the case in recent times with Parliaments MPs engaged in continuous poor behaviour.
