I DON’T insist on Biden at all.

Maybe not you specifically but I've seen a lot of peoples do.

many MORE people in this world will suffer, struggle and die under Trump than under Biden. It’s just math and all your ideology is VERY empty in the face of it.

See, I think this is where we disagree.

You operate under the assumption that the things that the Republicans want to do couldn't happen under Biden, presumably because you think he would block Republican policies, but knowing what I know about Biden and his policies, his willingness to "reach across the aisles" and give concessions to the right, his tendency to passively letting Republican bills pass without doing anything about it even when he clearly have the power to, his failure/unwillingness to roll back Republican policies from Trump's last term let alone the ones that he expanded instead, etc.... I'm telling you honestly, I don't believe that for 1 second.

I have not seen ANY evidences that Biden would act against Republican politics.

Heck I haven't seen evidences that he wouldn't do a complete 180 and start supporting Republican policies that he used to denounce, it wouldn't even be the first time he does it.

In your arguments in favor of voting blue, you (the peoples who tell everyone to vote blue) always use this assumption that Biden couldn't possibly be as bad as Trump as an axiom, as if it was just obvious, you never bother trying to show that it's true, you never question it, I certainly haven't ever seen any of you questioning it or trying to demonstrate it. You just treat it as some sort of fundamental truth to the point you don't even seem to notice that you are using it sometimes.

I haven't seen any reason to believe that this assumption is true, on the contrary.

When I look at the 2 last US presidential terms, I don't see a bad president and a worst president, I see a bad president who tell you that he's gonna to terrible shit and does exactly that and an other equally bad president that pinky promise he wont do terrible shit but then do terrible shit anyways and blames the other bad president for it when he get caught doing terrible shit.
