I’m not in history (I’m in Spanish) but my undergrad was in history and Spanish and I have professional experience in teaching rhetoric at college level so I thought I’d throw my two cents in. I agree with what the others have said, I honestly don’t think your opening paragraph is as strong as you may think it is. Think about your audience - it won’t just be the professors you’ve spoken with and the first paragraph is key in setting the tone of how they view the rest of the statement. It should have a hook, yes, but it doesn’t need to be a whole paragraph. You need to be concise and precise with language. The example statement from Berkeley which is often used as a holy grail statement does this most of the time, however, there are a couple of paragraphs in there which add very little to the general narrative even there. This first paragraph just feels like an attempt to mimick a more artistic style but it’s lacking any real substance.
You also seem to struggle to take any constructive criticism from other members in the forum. Think about what a PhD entails - you will be critiqued on all of your writing and scholarly output continually and this will make you better. The feedback people have given you (including me) is to try and help.
Just my $0.02, I am not trying to cause any issues.
