I don’t know who offended you by not wanting to shake your hand, but I’m not as committed to working out this issue here as you are. So I’m just gonna go ahead and nod and smile.

Whether or not handshakes are “weird” is an entirely subjective opinion based on your personal views and related to how and where you were raised. It’s a little interesting to me that you’ve conflated what is a polite way to indicate a dislike for physical contact with strangers without rebuffing a handshake nobody thinks to ask for ahead of time with a “passive aggressive” way to not interact.

I was genuinely hoping the pandemic was going to put an end to the whole weird handshake thing forever. I know people who transitioned to the elbow-bump thing and it was always all I could not to say "Hey, you know we could just... not insist on touching each other for no reason, right?"
