"What a pity that the Native Americans didn't think the same."
Indeed. Look at what happened to them; would any white person in their right mind allow the same happen to themselves?
"And when your family came here they were taking land from the Native Americans, and you brutally slaughtered them when they tried to defend their culture and heritage."
Actually European settlers saved the enemy's women, children and the wouded. Guess what? Indians didn't. They were savages.
"Give me a break. The only ones losing any great amount culture are the minority cultures."
Whites are a minority.
"Also, white people have CULTURE? I did not know that."
Sure. Such things as human rights, abolition of slavery worldwide and democracy are some of the achievements of said culture. Whether you value bongo drums or Chinese traditional medicine above these is a matter of opinion.
"When the hell did multiculturalism become a bad word?"
When people realize what it actually means.
"Racist how, exactly?"
Multiple remarks of whites "having no culture".
"Its part of this whole "living in harmony" thing that the progressives have been trying to promote for years, that assholes such as yourself have been so successful in keeping down."
Why does "living in harmony" require massive immigration of non-whites into US and Europe?
