It's ridiculous, isn't it?
I think back on some things I did in my earlier years and wow, I could be burned at the stake by society these days! And I wasn't a party girl either.
I've been seeing some news about Molly Ringwald bringing up the movie 16 Candles and the scene about how the drunk girl was passed onto a boy to do what he wanted with her. That's pretty much what happened in the 1980s if girls got drunk. It's not right and we think about it differently now then it was thought of back then.
I still think the allegations from decades ago are frankly silly. If the young Brett Kavanaugh acted exactly as Dr Ford described we might have cause for concern, but even then we're talking something from decades ago and if he has mended his ways (and the number of women supporting him suggests very strongly that he has) there comes a point when we have to say it's no longer relevant.
As you quite rightly say, there are probably few very of us who could survive our entire life histories being examined, through the lens of today's sensibilities, and not end up crucified in the court of public opinion. Particularly when "public opinion" primarily means people who have a vested interest in discrediting you by whatever means it takes.
My concern remains over questions relating to his testimony. From what I can tell he testified that he was never a heavy drinker while some people seem to take issue with that statement. Then there's the question of just what is meant by "boof" and "devil's triangle". He said "boof" related to flatulence while some say it relates to sodomy, and "devil's triangle" was apparently a drinking game but other references suggest it refers to a threesome.
Just as the issue with Bill Clinton was less about just what Monica Lewinsky was doing under the desk and very much about whether he lied under oath, so my concern with Brett Kavanaugh isn't what he did as a young man (I was pretty silly in my younger days too) but whether he lied about it under oath.
