Anti-Christian bigotry is the last fashionable hatred. It is easy for Davenport's Christophobes to pick on Good Friday. What's the worst that could happen? Angry phone calls and e-mails? Town-hall meetings? Maybe public protests? But, in the end, progressive commissars realize they will not pay much of a price - in fact, they will be celebrated by liberal elites for their "enlightened ideals."
The same standards do not apply to Islam. Davenport's multiculturalists would never dare to remove say, Ramadan, from the calendar and rename it "Fasting Month" for fear of offending Muslims - and possibly triggering a fatwa. Self-preservation - and cowardice - dissuades them from attacking certain religions.
Christians, however, are an easy target. They do not believe in jihad or suicide bombing. Unlike radical Islamists, they espouse the rule of law and human rights. They accept persecution - even state-sanctioned persecution - as part of their religious burden. Liberals realize that Christianity is a genuine "religion of peace." This is why they do not fear systematically smearing it.
