The same thing - show kindness and understanding instead of attacking you for "letting Trump win."
It would also be great if they made an effort to primary candidates one can vote FOR instead of relying on WBNMW and delaying the inevitable (which, as I said, will likely lead to an even worse Republican presidency.
But getting them to vote third party/not at all doesn't seem possible at the moment... because they don't believe something better is possible. See this reply to my comment as an example.
And you could try reasoning with them, but... haven't you been trying that already? Unfortunately, most people don't go by reason.
Maybe they need to be shown that something better is possible.
They need hope in a better future one can pursue.
We all do.
