Actually they're saying he thought them Muslims, not blondies.
This revenge thing, it has me puzzled. I have to think it's an excuse to act out their murderous impulses. People, many people, if they feel obligated to do so, justify their actions as it were after the fact.
An Australian physical trainer takes a notion to take revenge against Islamic terrorists who have been perpetrating deadly attacks in Europe by finding a soft target nearby, i.e. New Zealand, where the strict anti-gun laws of his native Australia didn't (at the time) exist. He conjures a plan, executes it, killing dozens.
Then Islamic fundamentalists of some flavor in Sri Lanka decide (presumably) to retaliate for this one guy's murderous wet dream by killing 350+ in Christian churches on Easter. Revenge. Seems the Islamic fundamentalist murders have an m.o. they favor, being simultaneous coordinated attacks using suicide bombers. It's their finger print. Why is it that Islamic fundamentalists are so enamored of revenge? They're not alone in this, but they seem to be much more prone to it. I heard that some of the suicide bombers in Sri Lanka were well educated children of upper class people in the country. That has me seriously baffled... and curious. What did happen there?
I live in Trinidad & Tobago (google it) which is extremely diverse. We had an attempted Islamic coup in 1990, just before Sadam's invasion of Kuwait. Naturally all international the press that were present fled to bigger stories. Police executed, minister killed plus others, prime minister and others held hostage, police headquarters gutted by fire. Curfew for months. Smelt the tear gas and heard the semi-automatic fire.
I laugh at some fools here who make these juvenile blanket statements on topics they're unknowingly ignorant about and just repeat sources. I have had close relations to the extent of dating with Muslim, Hindu, all types of Christian, Chinese, Indian, African, European and combinations of these. This is my culture and we celebrate each other's religious holidays, Eid, Divali, Christmas, Easter.
It came as a complete surprise to most citizens as we were so tolerant and diverse. How could this happen here. I remember being at work when we saw the takeover of the TV station being broadcast and my fellow workers wondering what to do. Seriously, my advice and action was to sign out work, head to the grocery, gas station and stock-up. Came in useful during the curfew. People were actually going to remain at work.
I said all of that to emphasize that the Muslim terrorists that attempted a coup were overwhelmingly converts. A fair percentage came from the school I attended as a teen. It was the most prestigious school in the country at the time and was Catholic.
So a prestige Catholic school ends up producing the plotters and operators of an Islamic national coup. In fact the 2nd in command of the coup was one of the top 10 students in the entire country for his age group.
Go figure.
