Most Christians will not only denounce the crusades,
or the 30 years war, but also even such tactics as
bombing abortion clinics - in no uncertain terms.
Nor have I seen much evidence of sects which
promote these. One can't blame religion alone
for the violence in the near east, but it's a major
component.
I expect more harsh repudiation than I've seen.
Certainly, financial support for groups which have
any links to violent dogma should be stopped, by
anyone seriously claiming that Islam is a religion
of peace.
The whole whitewashing attempt on the term
Jihad is despicable. Like Crusade, it has far too
much negative baggage to be defended.
