Incorrect. That was the first documented abortion, yes, but we know for many reasons that it has been around practically since civilization itself sprung up.
What minority? Slaves were more of a caste than a minority, since various powers across the West practiced slavery and enslaved people of all races. It's a technical distinction, but an important one.
Ah, but you also said Trumpists want to return us to a time of no vaccines as there was in the Dark Ages. I'm pointing out that not knowing something exists and willfully suppressing them are two very different things. I'd also point out that the vast majority of Americans on both sides of the aisle get most vaccines, so this really isn't a point you should be trying to argue except as an exercise in futility.
Regarding your note about LGBTQ+ equality below, I'd say that's not accurate either. The Greeks and Romans were wildly into gay sex. It was considered normal. Many monarchs and figures of import were clearly into freaky sexual practices which we'd today consider LGBTQ+ categories, so it was in all likelihood treated differently, at least in part, compared to today.
