You sound more like a cornered sheep than a tiger. Read the fiqh and the rulings of what to do with he who abuses and slanders the Prophet.
And you can let go of Ta'if now..its been ages. The Prophet (sas) was in the beginning of his Prophethood with hardly a handful of followers hence Islam was in a state of non-violence. But once Muslims had gained ground in Madina and the commandments of Jihad arrived then we know very well what the Prophet did with the likes of Ka'ab ibn Al Ashraf and Abu Rafi'.
Islam gave Muslims izzah and authority but Muslims somehow, subhanallah, love to live in a state of opression and weakness ... constantly quoting Taif and other Meccan events when its clear in all of the Books of Seerah and the Books of Fiqh and the Books of Hadith that once the following Ayaah, and its likes, were revealed ... the 100% non-violent approach to Daawah was abrogated.
Warfare is ordained for you, though it is hateful unto you;... Surah Bakrah, Verse 216
Pardon my ignorance but how does any of that justify killing of innocent people. By all means go and confront the Danish cartoonist and the publishers but what right does it give anyone to go and kill any Danish person or anyone in the name of exacting revenge. This is just wrong and evil. It is not like the Danish Government or Embassy runs those newspapers. The people who carried out this terrorist atrocity knew fully well that their action would result in the deaths of innocent people (which sadly is the case in almost every atrocity). This makes all their crimes even more unpardonable. And you conveniently forgot to mention fatah Makkah where not a single soul was hurt or injured and everyone (some of Prophet's pbuh worst enemies) was pardoned on the orders of the Prophet pbuh.
