Islam make extremists using social media and the Internet to change public opinion?

I've heard many people saying that the extremist of Islam are very small portion of the actual religious faction yet evidence points elsewhere. My question is have you scroll the Internet or googled to look for Islamic atrocities lately? These terrorist groups have figured out that if they flub the Internet with fake pictures and propaganda that it begins to over cloud the actual factual evidence. They are creating a dancer fog of war. When you confront one of the supporters with facts they will turn the argument back on you and instead of discussing the topic will simply turn the discussion back toward Israel or the United States and are atrocities as well as pointing fingers at Christianity. So my question is have you looked recently through the Internet and googled to see what terrorist actions have been committed if you do select images and you will see 90% of it has been posted by Palestinian supporters and they are using the title Islam make extremist or atrocities to post propaganda and blame Israel. How do you fight a social war of propaganda
