Is it permitted to attend a non-Jewish wedding? Assume for the purpose of this question that the wedding is occuring in a non-religious location (such as a hotel). If it is permitted to attend, is it permitted to participate in such a wedding (such as by reading a non-religious poem).
Is there a difference between (for example) a Christian wedding, a Muslim wedding, and a non-religious wedding?
