Slonim,
its not me its the SHu”A:
“אֵין יוֹם הֶחָג אָסוּר אֶלָּא לָעוֹבְדִים בּוֹ בִּלְבַד, אֲבָל הָעוֹבְדֵי כּוֹכָבִים שֶׁשְּׂמֵחִים בּוֹ וְאוֹכְלִים וְשׁוֹתִים וּמְשַׁמְּרִים אוֹתוֹ מִפְּנֵי מִנְהָג”
The Shu”A is talking about your local peasant, not your educated Wiki reader…
If you have a different understanding please explain.
Christmas is definitely a religious Holiday as per anyone. Simpy ask why many offended liberals are opposed to greeting “merry xmas” and just greet “Happy Holidays”. Did you ever hear anyone offended by a “Happy Halloween”?
