That is absolutely not the American way, at least according to American ideals. Using violence against people with whom you disagree or find offensive belongs in theocracies or uncivilized areas of the world. America is defined by respect for individual rights, which includes the right to express unpopular or offensive sentiments. We also pride ourselves on the fair and impartial rule of law.
Here on this site, everyone criticized the Islamic radicals burning buildings and threatening lives over a cartoon. Everyone seemed to agree that no matter how great their outrage, they were wrong to use violence. But when the issue becomes something WE care about, suddenly new rules apply.
Suppose I said that Mohammed was a child molestor, and a Muslim citizen overheard and broke several of my limbs in response. At the trial, the judge sentenced the defendent (with a wink and a nod) to a $50 fine. Oh, and the judge coincidentally is also named Mohammed. Would that be the American way?
"Suppose I said that Mohammed was a child molestor, and a Muslim citizen overheard and broke several of my limbs in response."
If I went to a Muslim funeral yelling Mohammed was a child molester, I'd deserve to get my ass kicked. You see some free speech right issue here?
