I know the feeling all too well ~ my youngest is two. I hope your little one settled okay for you in the end!
I agree about the generalising entire groups of people... It is horrible to see and it is basic common sense that not everyone is the same. All throughout history people have done just that and it has caused untold amounts of damage.
Unfortunately, I have read a whole lot of people generalising Palestinian people and essentially lumping everyone in with Hamas. A lot of these posts seem to stay up but obviously the most directly offensive and vile posts are removed but sometimes not as quickly as others directly criticising Israel.
There is a difference between Jews and Zionists. I think that is an important thing to point out (before anyone jumps on me for that!) There are always Jewish people marching in the demonstrations and being very vocal about wanting a ceasefire and that Israel needs to stop being an occupying power. Plenty of Jewish people have been attacked in Israel for speaking out. Whereas, it seems to be that Zionists are the opposite.
I think that the issue here is that people are disgusted with the actions of the Israeli army (to put it mildly/politely!) as well as being disgusted with the Israeli government. Then throw in the actions and continued behaviours of the illegal settlers, for example, and the people blocking aid trucks preventing starving people from accessing basic food and other essentials... it is these issues, along with a couple more, that people are criticising.
If only some would realise that everyone is human. All lives are worth exactly the same. But sadly I don't think that is going to happen as so many have it deeply entrenched that some are worth more and some less, it seems.
