First of all, I’m an Israeli, so take everything I say with a grain of salt, and I’ll try to be as unbiased as I can. Hamas, as opposed to Russia (I don’t say Israel because a lot will disagree), is an internationaly recognized terrorist group, which was elected* by the people of Gaza after Israel pulled all civilians and military from the Gaza strip, Hamas has made it very clear that their sole mission was to eradicate all the jews (not Israelis or zionists) from Palestine (and I’m not sure about that - also the world). So an Israeli supporting Hamas would be very problematic, Imagine an american supporting Al qaeda right after 9/11. And I just want to emphasize, supporting Hamas is not necessarily supporting Palestine and vice versa, myself I think that any hamas operative deserve to die, but I really hope and dream for the day that the Palestinians would be our peaceful neighbours. *elected technically, as they drove fatah, their main competitor and more moderate towards israel.
I try to keep my ideas and opinions out of this conversation to keep it unbiased, but the reality I see, living in Israel my whole life is that support for a terrorist organization is directly related to terrorist activity, for example we’ve seen it in 95 when support for a radical right wing Jewish terrorist group quickly ended in the assassination of the prime minister Itzhak Rabin, and Hezbolla supporters are easily recruited by Hezbolla to report where Hezbolla missile hits so Hezbolla can correct they’re aiming. As much as I understand,just supporting hamas’ actions, as vile and horrible as it is is free speech, but the road from there to actively take action in aiding Hamas is extremely short.
