It’s not goodies vs baddies, which I agree is very infantile. It’s oppressor vs the oppressed. Apartheid. Human rights abuses. Genocide. Massacre. Ethnic cleansing.
Creating a narrative for both sides in cases of oppression is always, without exception, for the benefit of the oppressor. “But this, but that” STOP. Open your eyes to what is happening right now, it is very clear to see and social media has shone a light on what is happening, and what has been happening for decades, more than ever before.
Other countries are frequently called out on their human rights abuses - the reason Israel is such a major issue is because instead of being condemned, it’s being backed and justified by many. That happened with South Africa too btw, right to the very bitter end - because it was in the best interests of some to do so.
I am glad that you agree that we should be looking at the situation from a wider geopolitical lens, and identifying all the ethnic cleansing, genocide, apartheid, human rights abuses and massacres going on.
It might help to consider, as you have claimed that only Israel is 'backed by so many', what the relative picture looks like in a wider sense.
Israel has a population of around 9.2 million, of which around 6.7 million, or c 75% are Jewish. Arabs (which includes Christian as well as Muslim Arabs) make up around 20%, and the remaining 5% are mixed.
The global Jewish population is around 14 million.
That figure is still lower than it was in 1939, thanks to the Holocaust, which murdered 2/3 of European Jews in under 6 years.
By comparison, there are 1.5 billion Muslims globally, or over 100 X as many Muslims as there are Jews. Since 1948, the number if Palestinians has gone up by 500%. Which is quite impressive, for a group of people that is claimed to have experienced genocide. Certainly one of the less successful genocides. 
There is only 1 Jewish state, and no other state where Jews are a majority. For example, in the UK, Jews make up 0.4% of the population.
By comparison, there are 49 Muslim majority countries. Many practice Sharia law and in many, non-Muslims, if they can live there at all, are treated legally as second-class citizens.
There have been a number of inter-Muslim massacres and genocides. Human rights abuses against LGBT people and women are unfortunately common. Try being an Iranian woman who wants to show her hair or a Saudi woman who wants a normal life.
Anyway, I'll leave it to you to decide who you think has more backers, globally - Israel, with its Jewish population of under 7 million and a global Jewish population of 14 million, or the Palestinians, supported by 1.5 billion Muslims, across 49 countries?
But sure, it's a real David and Goliath struggle, and Israel is the Goliath here, in your head.
