No it’s not and the GP is being a overly sensitive for no good reason. It’s a relatively recent sect of Judaism with a well known insular “ultra-orthodox” (more formally Haredi Judaism) Jewish community in New York, primarily Brooklyn and Israel. This is similar to something like the Amish, and pointing out something about Amish furniture or dairy businesses doesn’t make it automatically racist.

Because they are an insular group they are known culturally in the US for their retail enterprises. B&H Photo-Video being the most famous one. Go there now (bhphotovideo.com), you can’t even order during Shabbat.
