I agree to the original poster, however i’d like to make a distinction
between small products(a knife $3.00)
& larger products(ovens & cars of course)
also some stuff are unavoidable(not knowing)
& some stuff people knowingly buy!!
Especially expensive stuff.
If we can do this when the Holocaust(Hashem Yikoim Domom)
is still fresh in our minds,
I dont know what to think about these people!
Just like there is a chiyuv of Hakoras Hatov
there obviously has to be a Zechiras Hora
Like we have w/ amaleik Y”S (& if i remember correctly)
the Gaon brings that The germans are amaleik!!!
