What do I do?

He’s allowed to hold alternative political views. He’s allowed to discuss them. What he isn’t allowed to do is make family life intolerable.

Okay, so? The area was historically a Jewish homeland. Jews lived in Judea. After many centuries of dispersal by various conquerors, Jews have regained rule over their homeland.

I think the bit about Israelis "deserving 7 October" is the horrifying part. Why does he think its acceptable for any armed force to rape women and parade their corpses naked in the streets? That's part of what he's saying was deserved.

https://www.un.org/unispal/history/ if he feels you are listening to him maybe he will lay off a bit? Maybe ask him what he wants you to do?

I think he needs to respect that you have different views but also it might help to try and see where he is coming from and check where he is getting his info from. Have you read up on the history of how Israel became a state, from independent sources, rather than what you were taught as a child etc? He may be feeling very conflicted about his identity/what’s going on and how to deal with that. I’d set boundaries about appropriate times to talk about it, but also rather than just always dismiss him try and learn something about why he is feeling this way too.

Does he realise he’s distressing you?

Is your partner/his father support you.

Does he get an allowance and can you fine him every time he ignores your wishes?

I also think to need to blank him / leave the room.

it sounds so hard, but it might be helpful to explain what you have / haven’t done. Teens can be such buggers..

This

He is being a teenager, but if it’s at the point it’s distressing other people he needs to knock it off. You are entitled not to be berated in your own home.

Try to gradually work on helping him understand the world is a complex place, but the chances are he’ll get their on his own.

A lot of it will be peer pressure I suspect.

He's a teenager. If it wasn't Palestine it would be veganism or something else. All teenagers need a badge to wear. They are finding their own identity which usually means the exact opposite of their parents' beliefs and identities. There will also be (in many respects rightly) a lot of support for Palestine among his peers and he is desperate not to be the odd one out. Being the odd one out is identity suicide for a teenager, even though they all claim to be individualistic. I'm sorry he is ranting and making your lives miserable. I went through it with my son for different reasons. Leave him be and he will eventually find a level.

What country does he expect Jews to live in the Middle East without serious risk of persecution? Anyway.
He is rebelling against you all which may be a normal part of growing up and separating. I think you have to basically remain neural and not rise to the bait. His view is oversimplified and immature but there’s no point arguing. It may not really be about Israel more about reacting against his family.

Does he realise children were killed during the Hamas attacks on Israel? Because if he thinks children could possible have done anything to deserve being murdered then he's an utter shit.

His view isn't unreasonable but of course he's being unreasonable to keep bringing it up when you feel so differently.

I would focus on explaining how this is affecting family relationships. Perhaps there's a group he could join where he can express himself.

He may be struggling with the atrocities happening in Gaza and genuinely having a bit of an identity crisis.

Without wishing to seem to trivialise this, imagine he's constantly banging on about veganism. Lecturing and posturing over every meal and trying to rile the family up for an argument about eating meat every night.

What would you do to shut him up?

Do the same thing for this.

I think the sensitivity of the subject is, understandably, clouding your basic parenting instincts.

You do have to respect their right to have them however. As I said you don't have to agree with them, but we lice in a democratic society with freedom of belief, therefore you do have to respect that they are entitled to those beliefs and opinions.

Whilst I agree in the fact that we don't have to respect the person or opinio, I respect the fundamental right for someone to hold opposing opinions to mine, even if they are abhorrent.

Set the boundary as others have said and when he starts on it again start singing and dancing or put your headphones on.

At its root this is about addressing a behaviour (talking over you when you've set a boundary) rather than the topic. All kids think they know it all.

I agree with this. Taking out the topic that is causing the issue as that is arguably irrelevant on some level, he is an adult living in your house and he needs to respect that. If he’s behaving in any way that is upsetting, distressing etc and won’t moderate his behaviour, you would treat it as any other breach of what you find a acceptable.

You tell him that he can have his opinions but you arent going to discuss the topic under your roof any more. Its your house and your rules. Any time he brings it up, shut the conversation down immediately. If he refuses to stop ranting, then implement consequences (turn off the wifi etc) just like if he broke any other house rules
