This so-called "kosher for Pesach" ice cream is being advertised all over and marketed to a Jewish public who is no doubt completely unaware that it is 'treif' even when it's not Pesach.
Torah Jews should never buy Ben and Jerry's ice cream. Our money comes from Hashem and we are responsible for how we spend it and who we support with it. A portion of the money you are giving them is spent to promote and legitimize and even 'sanctify' a particularly heinous sin and to foster pride in that sin. Do you really want to explain to Hashem why you were a contributor???
From the Ben and Jerry's website:
June is Pride Month, and here at Ben and Jerry’s we’ve been supporting Marriage Equality for over 35 years. Our commitment to the LGBTQ community is grounded in our company’s core values, ....The page goes on and brags about their deep involvement in promoting this aveirah, but this should be enough to convince you. Please warn others who might not know.
Wishing everyone a very happy and KOSHER Pesach!
(PS: Still in doubt? Just google "ben and jerry's supports gay pride")
