I am concerned as a couple of posters fashioned to refer to R Moshe’s S-I-L somewhat derogatory. I understand that you might disagree with him on some issues, or even doubt his veracity when quoting his F-I-L, suspecting that he puts a political slant.
I wonder – do you have any factual basis for your attitude:
– do you have evidence that R Moshe did not verify quality of the semicha of the chatan, so you don’t use R-?
– do you have cases, or even a pattern, of other witnesses contradicting R Tendler’s reporting of R Moshe’s words?
Also, keep in mind that people in the family tend to talk differently between each other. It is possible that R Moshe was focusing on the psak when talking to outsiders and revealed more of the underlying reasoning in the family.
Just a sevorah, I do not see a contradiction between a strong position against abortion and a position against government interfering in religious matters. R Moshe had Soviet experience with both murder and religious prosecution, so no doubt he understood policies here – and better than one-issue advocates in US.
