Sudan is the classic example. 90% of Americans could barely point to it on a map. Most Europeans have no idea there's a civil war raging for the last 3 years and created millions of refugees, killed hundreds of thousands, subjected tens of millions to famine.
The problem is you can't paint it as "good guy" and "bad guy"
Israel is a country without oil. Over 2 years, it killed 60,000 people in Gaza - about twice as many as the Iranian regime killed in 2 days. The former was described as genocide, the latter was widely ignored. And for 2 years, Israel's war against Hamas was the headline story every day on every media outlet in the world. There was no end of people screaming for intervention.
You're right, no one pays attention to Sierra Leone, or Sudan, or Myanmar. And no one here or in the media would care that some country was fighting a war with the Iranian regime either, as long as the country country fighting it wasn't populated by Jews.
My country doesn't sell Iran any weapons they used to kill protestors and independentists. I am allowed to boycott Iranian products, like my father was allowed to boycott SAF products. I just want my country to stop selling weapons that help killing civilians and end up in west bank terrorists hands. And be allowed to boycott what the fuck I want.
Iran's mass murder after the protests was not ignored. We had a mass protest in my city. I'm not sure if you can call it genocide because it's their own people, the same race and identity. It's certainly mass murder and terrible but not an attempt to change the population racial makeup. Thus the label genocide doesn't qualify, but yes the actions are morally equally bad. Just a different label.
The reason there's less attention is twofold:
First of all our countries support Israel so we are complicit. That calls for more protest among us who don't agree because there's actually something we can change. Iran is not going give a crap when they see people marching in protest in Europe.
Another thing is that Israel has no business being in Gaza in the first place. Iran's government unfortunately does have a legitimate claim to governance in Iran.
I'm not against Jews at all but I am against my country supporting genocide.
Also I don't think one country unilaterally bombing a place they have nothing to do with is the answer to any problem.
Why so many words to say "anyone who criticizes Israel is an antisemite"? If you really think Gaza gets too much attention, then instead of silencing others, why don't you just start talking about the injustices that you think are underrepresented.
But if it was a country without oil it would have been no more than a byline in the media, as if it were Sierra Leone or something, let's be honest.
