The Manning centre's questionnaire is a study in the use of "wishful" questions designed to illicit the response desired by the questioner.
I wonder whether the centre would consider the following questions as candidates for a public opinion poll:
Instead of "nothing is more important than family" (agree or disagree), how about "family is one of many valuable institutions";
Instead of "marriage, by definition, is between a man and a woman," try "the right to celebrate monogamy through civil union should be shared by all Canadians, regardless of creed";
Instead of "abortion is morally wrong," try "it is not the responsibility of governments to adjudicate controversial ethical debates" or "the sanctity of personal freedom is more important than the institutionalization of one or another moral code not shared by all citizens";
Instead of "learn from what worked in the past to solve problems," try "it is better to adapt to reality than to stubbornly cling to outmoded beliefs";
Instead of "better to implement small changes than all at once," try "if changes need to be made, better to act quickly than to be reactionary."
