Modern halakhists who permit abortion in cases where mother's life isn't threatened:
R. Yosef Haim (Rav Pealim EH 1:4)
R. Eliezer Waldenberg (Tzitz Eliezer 6:48 et al)
R. Shneur Zalman Fradkin (Torat Hesed EH 42)
R. Gedalia Felder (Sheilat Yeshurun 1:39) 1/
Everyone ready for a rant about Michael Chabon and his @HUCJIR commencement speech/ @tabletmag article? Here it comes.../1
Chabon's reduction of diversity and complexity (and more synonyms) to exogamy reflects his shallowness. Shtup someone of a different color, and you're "diverse". Endogamy is tantamount to redlining. Heterogeneity is no longer a metaphor; it's literally all about genetics.
