Stand against oppression—support the innocent.

I am feeling convicted about the war in Gaza. Originally the war between Palestine and Isreal was about land but the ongoing war now was initiated by the Hamas militants, they killed alot of people and there were speculations of them sexually abusing women but they denied it. Now the people of Gaza are suffering, I don't even know who to support because people who call themselves Muslims like the ISIS, Iran, Al Qaeda will be terrorizing people making Muslims look bad. There is even news of Muslims assaulting and killing Jews in the UK. Islam has been painted as a very violent religion by Islamic extremists, I am really confused and sad. Am I wrong for thinking like this
