Being stripped of his citizenship for doing what he did/does seems like a quite serious action to me.
Why do you care if KSA or any other Arab country starts to have a genuine dialogue with a neighbor like Israel where almost 25% of the population is Arab (Muslim and Christian) and 2/3 of all Israeli Jews being Arab Jews, in order to try to find a political solution to this tiring conflict that has given the region nothing but trouble?
Your beloved Turkey was the first Muslim majority country in the world to recognize Israel. They had very close ties for decades and have to this very day. You have not yet to date uttered a word about that yet you are blabbering about Islam left and right and Muslim unity, while attacking KSA for some imaginary ties with Israel.
No wonder that non-Muslims make fun of the state of Muslim affairs with hypocrites like you walking around and "preaching".
All the while Arabs are hosting the largest Somalian diaspora in the world and have helped it stay afloat economically not withstanding the fact that you people have had closer ties to Arabs than any other Muslim people historically and you have more influences from the Arab world than any other region of the Muslim geography, as well (by far). Strange people on PDF, I tell you.
