I will expect to be downvoted to hell for this.
What makes you say that? Plenty of people express support for the Palestinian people, including plenty of governments and heads of state, etc.
I personally think that being pro-Palestine means you should be anti-Hamas, since they are a brutal dictatorship that's plundered its people's resources to engage in a war with Israel that has destroyed their lives.
The main worrying thing is when someone is not pro-Palestinian, they're either pro-Hamas or anti-Israel.
As for the first para, I have very close friends who have been harassed for expressing support for plight. If you are a university student in the US today and said exactly what I have said, you can be found guilty as a terrorist-sympathizer. I have been downvoted to hell on reddit and elsewhere for putting it as mildly as I did here.
Personally, I don't use Reddit much, but this is definitely not the sense I get from seeing reading e.g. Twitter, in which there are plenty of extremely anti-Israel voices.
Remember - we're all seeing our own personal echo chamber of content.
The most common comments used to drown out actual criticism of israel and how to address its actions are actually the "aren't you glad we didn't vote for biden because he was bad for palestine" type. They will often be 4-5 of the top comments. Similar tactics are sadly used when discussing the crimes of the attack by emphasising the vileness of the acts in detail (despite both groups having plenty, and the world knowing both) and twisting the knife to make it too painful for people to engage with the discussion to exhaust them.
Let us not forget Israel has had a citizen driven hasbarah app which gives citizens "goals" (pre pasted propaganda messaged they are expected to post on their accounts) every morning to carry out online for over 7 years (reported by haaretz) https://youtu.be/iYzVOlcENZ4?si=IrN3FALmKVvIYkNJ I imagine it is much more discreet and efficient now.
