It's the latter.
Arguably a stupid mistake in retrospect, but all I said was that genocide against LGBTQ+ people is evil because genocide is evil, period.
I believed that opposing genocide was still in the Overton window and they hadn't gone full fash yet.
But then they told me who they really were.
That's when they began to constantly accuse me of voting for Harris. Because I opposed the mass killing of innocent people. I was already the oddball in my family for not spewing hateful rhetoric every day, so it was a believable narrative to them.
Maybe my brother doesn't believe for sure that I voted for Harris and just included me in his hit list because I oppose the killing that he wants to do. Either way, the end result is the same.
I'm calling my relatives right now to see if they can help, but other than that, no.
