Comrade, I appreciate your willingness to engage, but we’re materialists, not followers of the Great Man theory.
While there are many commendable actions Einstein took as a political activist, I imagine you’re not going to defend this xenophobia.
It’s fine if you included the Einstein quote in there as a note to end on, but it shouldn’t be your argument, since honestly, Einstein’s political views shouldn’t mean more solely on the basis of breakthroughs in physics (despite what Einstein claims). I would instead have frame challenged their comment to point out that the US claims to be such a “democratic utopia” but is definitely an “authoritarian dictatorship” itself. Maybe follow up with a quote about how any of the countries that didn’t do something succumbed to the US’ anticommunist efforts
