I am pretty easy going, but here are just a few things
Democrats
Republicans
The religious right
The irreligious left
Islamic terrorists
Islamic apologists
Race baiters
Trigger warnings
Diversity
Climate change
Political correctness
I could go on but I am loath to offend anyone...especially liberals, conservatives, Muslims, Christians, Jews, Atheists, people of colour,and/or college students (an oxymoron, of course, but they do exist and are easily offended).
