Multiculturalism, the characteristics of a society, city etc. which has many different ethnic or national cultures mingling freely political or social policies which support or encourage such coexistence.
That is a good concept on paper but sometimes this can lead to unnecessary social issues among others because of government forced multiculturalism like smuggling huff into a country in which it is illegal to have that substance.
This leads to more crime and bullshit that is on needed and unnecessary the phrase "follow the laws" isn't just a phrase it is a warning.
Also disrespecting different cultures is wrong however if a person comes to and burps at the dinner table at a restaurant calling the waitress a hot mama that's disrespectful.
