In a post on Curious Jew's blog, we were discussing the validity of platonic relationships.
As far as having female friends — is the advantage of their friendship really greater than the danger of inappropriate (in this context) feelings appearing between us?
and I replied
As a 50+ year old man who BT'd in his 40s, I will unequivocally answer that based on the experiences of my life the advantages of platonic friendship with women overwhelmingly outweigh the dangers of inappropriate feelings for me.
A third party responded:
Based on what concept in Judaism do you give this answer?
I was dumbfounded. I talk about the fact that you can and should see everything through the lens of halacha, but the idea that one should simply completely disregard one's life experience unless you can show that halacha supports what you have actually lived seems insane to me.
After a few minutes I answered (in two posts)
Chaim Bachem. Or Darchei Noam, if you prefer.
I'm sure the commenter will find this answer completely inappropriate because he thinks it misuses the concepts I brought up.
