I am just as guilty as anyone else on the following admonition: we need to make an effort to get to know who the h_ll is living right down the street from us.
You bet I profile, every time I leave my home, and we had better wake up now to the following inconvenient truth: there is no such thing as a 'moderate Muslim'.
There are lazy, non-practicing muslims, just like there are lazy, non-practicing Christians and Jews.
And, there are those faithful to Islam, who want to convert you or kill you, and they really aren't that interested in converting you.
...and what the "holdover" on them is. ;)
