Why Do Christians Have to Answer for the Horrors and Evils of Irac?

Why aren't there calls for all good christians to denounce this radical christian who killed 20 people in a church? Why is it that moslems have to answer for all violence by moslems, but christians don't have to answer to all the violence done by christians. A lot of christian nationalists in america want oaths to office to be taken on the bible, but then they're outraged when moslems take othes on the koran. I mean, it's preposterous the degrees of double standard tati their happening here. Conservatives also believe that killing a zi goat is evil, but killing a grown animal for sport, that’s good.
