Okay, fella - take a few breaths and relax. People are products of their times. The better ones fight for virtues and values they see as better at the time. They see an opportunity others do not and rally people around those.
Others they don't see and continue wi5h those norms, or they see the wrongs but don't believe they can rally people around fixing them.
Do not demonize people in the past who do not meet current norms. There will never be anybody who will meet those standards.
Judge them against the standards of their peers.
What if MLK did not support feminists? Would he now be considered scum, thus negating everything good he ever did?
Heck, i don't know if he had a stance on women's rights explicitly. Maybe he didn't. Is he evil if he didn't?

he literally addressed the national organization for women in 1966 and espoused their ideals.
giving a pass to the people from history is problematic because the same ideals of progressiveness that we pride ourselves on today were present in the past and people knew that it existed; they simply weren't as popular back then as they are now and anyone espousing them back then were treated like tankies of their own time.
giving them a pass only helps to excuse regressivism and anti-progressive sentiment like both the republicans and democrats (respectively) practice today; this is a key reason why we have trump as president today and probably jd vance tomorrow.
Yeah, nobody at that time knew slavery was wrong. Well, I mean, except for all the slaves, obviously, they knew, but there was no way for them to get their perspective heard because they were cut out of the political process. Who cut them out of the process? Well, uh, well you see...
There were plenty of peers, even UK and European ones, that opposed the US colonial project. Read Losurdo - Liberalism, a counter-history if you want an in-depth look at the debates of the time.
Product of the times isn't a great way to put it, but you can certainly make the argument that most people have shades of grey morality.
Science can back you up, too, as I teach social psychology and when you dig in, you find that normative human nature is pretty complex but generally very supportive for in-group and mildly empathetic even with strangers. It's only when you dehumanize a group do you get the worst behavior, and in all four cases you see that, be it slaves or indigenous people.
When you look at those times, it's people who recognized their humanity that ended up in the just side of history.
