That's not my assertion, nor the point of my comment. The point is that identification (and misplaced sense of ownership) makes us very reluctant to be convinced [1]. A point which you agreeing with.
Nonetheless, people adapt when change comes. Another example, only just in my living memory was "decimalisation" (and for other Europeans when the currency switched to Euro). My grandmother swore blind the world would end if they brought in decimal currency. Within weeks she was the strongest supporter.
In 1752 people in England rioted because the calendars changed from Julian to Gregorian. People thought they were being robbed of 11 days. When the day arrived everybody awoke, got on with their lives as usual and in no time completely forgot it ever happened.
EDIT:
[1] In fact people can be so challenged by identification they'll downvote the most polite and reasoned of comments to feel better rather than respond intelligently.
