You’ll find crazies wherever you go. I’ve argued against those same people too and pointed out to them that Hamas isn’t the rebel army for Palestinians. They cause great harm to the civilians too.
Lumping all criticism of Israel together with pro Hamas drivel only benefits Hamas. That’s what they want, to build legitimacy and hate towards Israel. You’re doing their dirty work for them. If you actually want to oppose them, call out the specific, explicit instances. Don’t rail against a Palestinian protest group – rail against the terrorist supporters who are trying to disguise themselves.
The IDF is wrong for killing innocent people. Hamas is wrong for killing innocent people. Neither of them are justified in it. Anyone who cannot accept all these statements is a bigot in some way and should be condemned.
Also, there seems to be very direct links between Netanyahu and Hamas. The NYT just reported the other day that Israeli officials allowed suitcases of money to go Palestine for Hamas to seize. Netanyahu used them to get into power and stay in power.
