Considering the source of this information is from a KNOWN TERRORIST SITE, yes, I'd say it's pretty biased.
It is funny that the author vows to desire the "end of the Palestinian/Israel impasse" when the Palestinian Authority nor ANY of its ilk would ever admit that Israel has a right to exist, and have never wanted a 2 state solution. The only "impasse" PA sees is Jews and Christians living in Israel.
The Israeili solider had a complete investigation done and was exonerated over Rachel Corrie's death. But, just like in America, when someone is tried and exonerated there are always instigators that will still claim that racism played a part in a conspiracy to cover up the truth (as in the recent George Zimmerman case in the US).
Rachel's death although tragic, could have been avoided by her remaining out of the way of a scheduled LEGAL demolition of known terrorist housing areas. The Intifada groups and PA have no problem when Israeli homes were demolished in Gaza and Golen Heights where thousands of Israelis were left homeless, thousands of jobs lost, and Israeli being deprived of 15% of it's economic income due to being forced out of Gaza which rightfully belongs to Israel in the first place.
