One of liberalism's many problems is that once an idea or program is proved wrong and unworkable, liberals rarely acknowledge their mistake and examine the root cause of their error so they don't repeat it.
Take multiculturalism ... please!
In a speech to a security conference in Munich, British Prime Minister David Cameron declared state multiculturalism a failure. For good measure, Cameron said Britain also must get tougher on Islamic extremists. Predictably, this has angered Islamic extremists.
A genuinely liberal country, he said, "believes in certain values and actively promotes them. ... Freedom of speech. Freedom of worship. Democracy. The rule of law, equal rights, regardless of race, sex or sexuality."
Cameron said in Britain different cultures have been encouraged to live separate lives: "We have failed to provide a vision of society to which they feel they want to belong." Here I would take issue with an otherwise excellent speech. It isn't that Britain has failed to provide such a society. Rather, many of those coming to Britain (and increasingly France, Germany and the U.S.) don't want to become a part of those cultures, which they regard as corrupt and anti-God.
Britain's policy should be to require -- yes, require -- immigrants to become part of a melting pot and not individual vegetables floating around in a multicultural stew. Otherwise, they should not be admitted.
When critics of multiculturalism and unbridled immigration warned of the inevitability of a loss of nationhood and national identity, they were denounced as alarmists, even racists.
The late British parliamentarian Enoch Powell suffered such attacks (and earned many kudos) when he repeatedly warned about the dangers of open-ended immigration without assimilation. In a controversial speech to a Conservative Party conference in 1968, Powell began his address, known as "Rivers of Blood," with what ought to be an obvious statement: "The supreme function of statesmanship is to provide against preventable evils. In seeking to do so, it encounters obstacles, which are deeply rooted in human nature."
Powell argued that when it comes to multiculturalism and immigration, Britain had failed in that mandate. Looking into the future, Powell accurately predicted what has come to pass from mass and uncontrolled immigration: "Of course, it will not be evenly distributed from Margate to Aberystwyth and from Penzance to Aberdeen. Whole areas, towns and parts of towns across England will be occupied by sections of the immigrant and immigrant-descended population."
Powell wasn't so much railing against immigrants, though his critics read it in those terms, but against Britain's refusal to integrate them into British culture.
