Hamas is a terrorist group. Not all Palestinians are Hamas. Israel is targeting Hamas. They have done their best to minimize Palestinian civilian causalities. It’s not genocide. If they were going for genocide, this would have been over with a long time ago.
The problem is, we as the general public, have gut reactions to things we don’t understand and aren’t directly involved in. This is made worse with misinformation and poor Internet literacy.
Another problem is that many Americans’ view points are sympathetic to terrorists. But, as I’ve heard somewhere “one person’s terrorist is another’s freedom fighter.” These people believe Hamas aren’t terrorists and are wrongly being fired upon, therefore Israel is bad.
Another group, Trump supporters and the like, will twist anything Biden does negatively because it doesn’t align with their narrative.
This makes me think of the sunk cost fallacy. I figure they are so heavily invested at this point that they are doubling down. If they don’t have Trump to back their views, they might realize being a bigot isn’t cool.
