I am a Muslim and completely agree with what you said.
The irony is that the Prophet was maligned, harmed and thrown stones upon, his response was always peace but the Muslims who claim to be defending the Prophet actually abuse people on facebook pages and forums. The question I ask is this. Does any of this result in something constructive? I don't think so, I have seen more people uttering bad words, being violent (which by the way is un-islamic). So what is the point?
If the Prophet was alive today, he would never even heed to these things. I do acknowledge that as a Muslim I get offended about such things, but there is a way to express one's views. Most of the Muslims today do not think about the outcome of what they are doing. I think that banning these websites actually spreads it out more, because people who had never even known about it would come to know of it.
We as Muslims have let a bunch of people get hold of the leadership of our countries and they are doing nothing for us. They just gobble up more money and deprive people of their basic necessities. The biggest Jihad is to stand against these Muslim leaders and demand our rights. If we as a people unite, these leaders cannot do anything. We have inflicted the current situation upon ourselves, by letting them take hold of our freedom.
