I very much believe in free speech. But in order for speech to be free you have to say what you mean without intimidating others into silence. Or it turns to threats or harassment.
This means I think you can talk about the situation in Palestine and the oppression. You can talk about Hamas and what their objectives are and how they came to power.
The problem arises when you start to say you agree with Hamas and it's methods and you want to kill Jews or Jews deserve what they get. (Which is what Hamas do believe so if you say you support them it gets problematic). There is a difference between sympathising with the Palestinians, understanding their right to defend themselves and explaining why they perhaps can't just protest peacefully and have no choice but to resort to more aggressive resistance and then going as far as saying you support Hamas and think what they are doing is right.
Likewise I think you can discuss Israel and it's right to defend itself etc etc. What you can't do is say all Gazans are terrorists and support Hamas and therefore deserve it. And then start talking about killing Arabs or Muslims. And I take issue with the Israeli government because this seems to be their current official line.
The problem isn't the subject matter, but the extremism and the racism. And the disinformation. Free speech is not a licence for disinformation nor abusing others.
I very much believe it's essential that people are allowed to speak because it's the best way to get people to understand the problems.
But the emotion levels, which are understandably high, often don't lend themselves to this. And I do think at times people push the point about free speech as a way to abuse people rather than to talk about issues. It's the difference between ad hominem attacks (to an individual or collective) and discussing the actual problem itself.
I generally feel that MN do a decent job over this issue because that tends to be the way they definite when deletions happen. Though I have been frustrated by certain conversations and how they got deleted.
I think it's been made harder online recently because of the online harms law.
I find the Israeli communications black out appalling. It is even worse that they gone nuts at Elon Musk saying he will support starlink services to recognised international aid agencies in Gaza so they can contact their workers and have blacklisted him for this. It's a total disregard for humanity that sits at the heart of that little cluster. It undermines their entire argument that they are just defending themselves.
