Shaking Hands – I am not a Rav (and I didnt ask one) but I think the obvious difrentiation would be that its not Derech Chiba, no? an easy out. Also, I am just way too lazy to go and explain for 45 minutes why I am not going to be shaking their hand, 2 seconds it’s done, and for the rest of the meeting they arent looking at you like you have horns on your head.
P.S. Don’t tell me they’ll respect you for it. I dont think they do.
