Dismissing them as "crazy" isn't only ableist, it's also counterproductive - they are literally some of the most powerful men on the planet, and they will keep doing everything within their means to achieve those goals, and worse, unless they are opposed.
All in all, a shit take.
Still happening, both in US and EU (couldn't find a good source on the UK, though I don't doubt it happens, instead have this horrible statistic Disabled people's Covid-19 death rate as much as 11 times higher than non-disabled people because we're not seen as worth saving), and certainly in most other countries too.
And this is just disabled people, Indigenous people (in Canada too, of course), immigrants in detention are still being forced/coerced sterilised, as well as several other marginalised groups targeted in different ways (like systemic racism that leads to higher mortality rates of Black birthing parent and babies during and after pregnancy, UK US Canada).
And to go back to what the op of the thread said, the Trail of Tears, is like the tiniest tip of a monstrous iceberg of ongoing genocide, and that monstrous iceberg is just one of many floating in the American ocean of white supremacist atrocity (and before the Americans get defensive, Yes, other countries do atrocities too, yes citizens there/here are also taught a whitewashed version of history that serves to maintain the state, you may not be alone, but you're absolutely no better than anyone else).
