“Its tantamount to spitting on them to not do it”
I beg to differ. If you politely explain to any man that your religion forbids shaking their hand, I’m sure that not only won’t they be upset, they’ll respect you for sticking to your religion.
And hey rabbiofberlin, you better check your Halachos. Look in your Mishna Brura and any Mussar Sefer about touching the other gender and you’ll find that it is Ossur period. Until now I thought you knew your stuff but to Matir someone to shake a man’s hands??? Surprising of you…
