My experience with this conflict has been that people have had to specifically demonstrate that there are more than two sides to this. Support for the Palestinian people or being against large-scale bombing does not mean one supports Hamas.

Take a look at how CNN vs BBC vs The Guardian categorize the conflict. CNN and NBC News describes it as the "Israel-Hamas War" (Reuters similarly uses "Israel and Hamas at war") while the BBC and Guardian list it as the "Israel-Gaza war" (and I'm pretty sure the Guardian previously used the same terminology as CNN).
