I know the Judaica store in every place I’ve ever lived has sold items that aren’t quite kosher. Kiddush cups not a revis, washing cups with spouts, “tallises”, klapim from who knows where, it is on the buyer to know these things. If they say tihs is kosher litchatchila then there could be an issue.
As far as bashing reform Jews, they do a lot of stuff wrong. They don’t know better. I’m going to give our friend here the benefit of the doubt that he is BT, other wise why would he be in a reform shuls bathroom on YK? Because if he were to just be making up things thats just richilus.
