Many defended Mr. Biden, saying he was from an older generation when social mores around physical contact were different.

I am 68, a bit younger than Joe Biden. But I am from a big Irish family and we are always kissing and hugging people. It was an expression of welcome and warmth. Now I understand in this MeToo movement that there are those who are uncomfortable with such intimate physical expressions. So now that Joe has been called out on it, it is up to him to show his changed behavior if indeed he runs for president, which I hope he does. — Sally Ziegenfuss, Pennsylvania

I’m a 70-year-old woman who has always thought that male attention that might involve non-intimate touching was something to be pleased about, even proud of. This is definitely a generational issue and younger women need to have perspective and understand that what was very acceptable in the past, even a couple of years ago, should not and cannot be judged by today’s standards. — Ellen Goodman, Massachusetts

Back in the ’60s this issue didn’t exist. It was a different time. When will we stop looking back over our collective shoulders, and move forward? — Whitney Devlin, 74, New York

But many others said Mr. Biden’s age was no excuse for his actions.

I am in my 60s. Regardless of age or habitat, Joe Biden’s touchy feely actions with women (and men, allegedly) are disgusting and inappropriate. I don’t believe they arise out of innocent affection, though he may have himself convinced. They arise out of unconscious male privilege and are demeaning and distressing to those on the receiving end. — Joan Weis, California
