I had the opposite journey. I used to be more sympathetic to Palestinian side until this war started. Most people and media around me are pro-Palestinian.
But it’s not the whole story. This is a situation where no side is clean or innocent. So many Palestinians support Hamas that it’s hard to have sympathy. Yes, they lived under occupation for decades, but learned all the wrong lessons - how to be just as bad as Israel.
The fight is more evenly matched than you suggest. Israel may be winning militarily, but Hamas has the better media presence, and is winning hearts and minds of people around the world. Every dead Palestinian benefits Hamas more than it benefits Israel. They know it, and use it to the fullest extent.
