You know the difference whether you choose to admit it here or not. Hamas seized power by a bloody coup in which they brutally tortured and murdered thousands of their fellow Arabs. If you recall Fatah ran in terror to Israel for protection. They are not legitimate and are brutal oppressors of the Gazan people. They commit illegal arrests, torture, honor killings of little girls, drug smuggling, prostitution, arms dealing, terrorism, embezzling, and worse. All of this is routine for Hamas. People in Gaza live in fear of Hamas.
