Maybe because in those wars our governments were not directly supplying weapons, money and political protection to a genocidal, far right, fascist, extreme government. Maybe because when it came to those other wars you are mentioning we were not watching our media and government officials twist themselves in knots to avoid calling out the obvious human rights abuses, clear cut violations of international law and utter brutality of the Israeli government. Maybe because those who were against the murder of innocent civilians in other wars were not being conflated with supporting terrorists or being antisemitic because they disagreed with the murder of children, bombing of hospitals, deliberate starvation of a civilian population, collective punishment of a nation and the attempts to completely eradicate a people. This is one of the worst genocides we have seen and what makes it worse is the attempts of the media, government and some people to completely dehumanise the Palestinians.
I'm not one of those who posts though I do like and support pro Palestinian posts. I don't bother engaging with the other point of view because for me if you don't support Palestine I actually don't even regard you as a human being worth engaging with. You lack morality and humanity if you can watch the decimation of a population and make excuses. Or like the OP you want to remain willfully ignorant as an excuse for your lack of outrage and inaction. Being reminded of the savage reality of what is happening to the Palestinians interferes with that and makes you uncomfortable.
There is a simple solution. Immediate ceasefire and the recognition and establishment of a viable Palestinian state. Without that there will never be stability and Israel will never be at peace. It is hypocritical to wax lyrically about Israel's right to exist and protect itself without also recognising the Palestinian's right to their own state and to self determination.
For those who say condemn october 7th its you who is showing moral and congitive dissonance. Watch the videos from Israel. Watch what the government ministers, the journalists and settlers are doing and saying. 60% of Israelis believe the government have not used enough force in Palestine. 30000 dead civilians, 15000 of them children and that's not enough force? So how many do we need to see killed before October 7th is no longer an excuse for genocide, 100,000 a million? There are those in the government and in the media who are openly calling for genocide of the Palestinians. This is not a war for them against Hamas this is about collectively punishing all Palestinians in Gaza and the West Bank (no Hamas in West Bank yet they are still being terrorised by settlers and soldiers) for what happened on October 7th. Kind of similar to how terrorists believe in collectively punishing citizens of governments they don't agree with.
Once again I don't really bother with arguing with people who don't support Palrstine normally. For me it's like arguing with people who support apartheid, the KKK or colonialism. Waste of time we are literally morally on opposite sides of the spectrum and i have no respect or patience to hear it. Its actually a good sign those people post OP. It means they assume you are morally redeemable. I have lost hope in the humanity of people like you. If you can watch Palelstinian children being slaughtered and it doesn't horrify you or you can make excuses when you watch Israelis deliberate destroy hospitals and target journalists as well as block access to food and water to the Palestinians then nothing can prick your conscience. Just like when we look back in history at atrocities that occurred in the past and wonder how it could have been allowed to occur, future generations will look back and see those ignoring or excusing the suffering and genocide inflicted on the Palestinians and wonder how you could have been so blind. You are standing on the wrong side of history.
