Multi-culturalism was fine when it meant that there were celebrations in each town and city that showed off the traditional dress, cuisine and arts of the various cultures. It's turned into a monster that has been used against our own culture - we dare not have any displays of Anglo pride or white pride, lest we be accused of racism, while everyone else is allowed to celebrate their culture and identity, and receives public money to help them do it.
What it's turned into is a society where "cultural identity" is used as a playing card to create an unfair advantage over other whose cultural background is considered 'the norm' (i.e., white anglo saxon), all other things being equal. I have a kid who will likely never be able to get a job where he wants to work, because he is white, anglo saxon and male. Preference is given to other candidates of other cultural backgrounds.
One of my parents is an immigrant, my other parent's grandparents were immigrants. Survival at that time required integration - learning the language, adopting the customs and language that were in use when they arrived. My grandmother once scolded my grandfather for speaking in their native language - telling him (in her thick accent) "We're in Canada now, speak English."
Integration helped people learn to get along, imo, and I don't see the same effort on the part of more recent immigrants to try to get along with the people whose country they wish to make their new home. I don't know how many Somali and Saudi women I've tried to help with their newborns, who cannot communicate in English or French. They keep to their own kind - they don't want to get along with us, yet we have to bend over backward to accommodate them.
That being said, I agree with you, Joliette, that the WTS made a mockery of acceptance of all races, languages and cultures. They International Conventions™ used to have a highlight ceremony where people that came from other countries would be paraded around in their national costume and we all clapped like trained seals, because we were told this was how it would be in the Paradise™. Yet, the next day, those costumes were put away and all those foreign delegates were dressed in suits and dresses like everyone else.
