Abusive or assertive?
Probably both. The question isn't whether an agent sometimes acts rudely, but whether they're in the right place--a place of likely Muzzie malfeasance.
I am a "refugee" from the Lodi, California area, and I blame US immigration for allowing undesirable people into the country. I sold my home and moved away, when it appeared that the area around my home was becoming not a good place to live.
I can remmeber when "multiculutral" was not a dirty word.
In our area, we have had Mexicans, Chinese, Japanese, Skihs, Filipinos and others. In the past, these people have added to the good of the community, and they have not been a police problem, with the exeption of some Mexicans, but even so, the good far outnumbered the bad. Still, Mexicans have brought good to the community.
In the USA, we have never seen any group of people with so little appreciation for human life as the Muslims. With Muslims, naturally comes terrorism, it seems. We have read about savages, but we just have not been prepared for anything like Islam in the modern day world.
