feivel: My “smart aleck examples” were for the purpose of starkly illustrating the dangers of what appeared to be the foundation of your post. That it was mutar to shake hands with women.
If I may, you misstated. We can talk about whether there is such a Shittah that it’s Muttar and how legitimate that Shittah is and under which circumstances. Even if we would decide that it’s Assur, being Halachically incorrect is not the end of the world nor worthy of derision. Worthy of correction, certainly, but not being rude.
What you (very correctly, IMO) railed against is the notion that it’s actually Assur, but that we can do it anyway to save face. Such a concept is the beginning of the uprooting of the entire Torah.
