a "Radical" Islamist is no different from my vantage point than an Atheist, I believe a "radical" Islamist is a non-believer.
*neither value a human life as sacred and are willing to kill, on a State level or individual level.
But aren't you then just making exceptions based on your subjective concept of who knows god and who doesn't?

Institutionalized Islam is a terrible thing. Does that make individual Muslims terrible people?
Institutionalized Christianity is a terrible thing. Does that make individual Christians terrible people?
The answer to each of those questions should be "no".
