The AC asked about people killed "in the name of Christianity", not people killed by Christians. Of the ten incidents in the list you linked to, you can scratch #10 (Timothy McVeigh), #9 (The murder of Alan Berg), #8 (Suicide attack on IRS building in Austin, Texas), #3 (Knoxville Unitarian Universalist Church shooting), and #1 (Wisconsin Sikh Temple massacre). These were acts committed by people who were presumably Christian, but who did not tie their acts to their religious beliefs.
As for the others on the list -- OK, point made. On the other hand, I don't recall mass rallies in Christian cities praising the perpetrators.
