Sure, and I’m sure you would have spoken out against slavery in America and Nazism in Germany too.
The truth is, most of what we are is determined by the context of our environment. I’m sure if you, as you are now, were somehow transplanted in that time somehow you might be right. But if you lived in that context there’s no guarantee you wouldn’t have gone along with whatever everyone else was doing. Whether that’s seeing Jesus as innocent or Jews as people. Maybe you would’ve been the few that did, but maybe not. We can’t say because you’ve never been in that context.
But considering even Christ’s closest friends abandoned Him and denied knowing Him, I’m not confident of your chances.
