Is this joking about Norwegians?<br /><br />"China is a symbol of peace, meanwhile it owns the absolute power to uphold peace. With over 1 billion people, it should have a greater voice on the issue of world peace. In essence, Norway is only a small country with scarce land area and population, but it must be in the minority in terms of other relatively large numbers concerning the conception of freedom and democracy. Hence, the selection of the "Nobel Peace Prize" should open [sic] to the people in the world instead of engaging in "minority" type of the [sic] so-called presumption."Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-44526457991176106692011-09-22T14:54:32.504+03:002011-09-22T14:54:32.504+03:00But joking about Norwegians must be ok, they have ...But joking about Norwegians must be ok, they have so much oil and winter olympics gold medals!?!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-66072875771285494402011-09-21T21:25:31.495+03:002011-09-21T21:25:31.495+03:00Yes, talking about contradictory data is not a per...Yes, talking about contradictory data is not a personal attack. My objection is against the comments about "chinese style" and similar. This can qualified as racial or national attack. So I'm asking people to refrain from such statements.<br /><br />Being an international forum, we need to be sensitive to other people feeling. I recall another case some time ago when a seemingly innocent joke about one of the European countries provoked quite angry reaction from a respectable person from this country.Vladimir Koifmanhttps://www.blogger.com/profile/01800020176563544699noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-30559011454290636442011-09-21T20:58:09.746+03:002011-09-21T20:58:09.746+03:00Well this is NOT a personal attack at all.
