DY, Las,
“I think he quoted R’ Yaakov that it was proper no to wear the talis openly.”
“It’s a מגן אברהם in סי’ כ”ה, also brought in משנה ברורה.”
True, but Rav Yaakov was speaking in terms of wearing it in America, as some claimed the the reason given by the MB/MA is not relevant nowadays.
(However, that may depend as well in the neighborhood, and is also possible nowadays is diff from Rav Yaakov as well. In a generation that people out there wear everything and anything – everything goes! So why is a talis different than a one wearing purple hair and a nose ring etc, in terms of arousing any antisemitism..)
