Biracial people: How do you get offended by racist remarks?

Well i'm Chinese/Dutch and i've only been called remarks on Asian people because i don't look white at all.
I only get offended if people i don't know say offensive things. (If it's someone i know he/she's probably joking if not i would say something about it.)
I do get annoyed sometimes because there is a lot of China-bashing on the internet, like on a Dutch news website before there was a story that was about one Chinese person commiting suicide every 90 seconds, and there were people (who probably have never been anywhere near the place) saying i hate that disgusting country etc.)
Well congratulations China has 1.3 billion people ofcourse you're going to have many suicides. And China is 65th on suicide rate per 100.00 people, so why is this news? I guess you already know.
And all of this hate is based on the news and ignorance, that's just stupid.
Sorry i might have gone a little off topic here just my point of view and what irritates me.
