I find it pretty amusing when people say some kind of variation of "we all have our problems" or "who are we to take the moral high ground" as if we have all beaten or abused our partners and what not.
Same thing with the Mitchell Miller situation. While I think it was a minority of people, you still had people saying "as if you didn't make mistakes when you were a kid." Like yeah I made mistakes as a kid, but verbally abusing and bullying a kid with developmental disabilities was assuredly not one of them
You may, however, be missing a larger point that's being made. Your opinion (as stated) is coming from a position of moral certainty, and you are equally certain that you, and everyone else, can be the arbiter of what is morally acceptable and what isn't. For example, your post that I quote here shows you stating that "abusing a partner" is morally unacceptable and that "verbally abusing and bullying a kid with developmental disabilities" is morally unacceptable, whereas "ma(king) mistakes" is okay.
Now, it may indeed be the case that 90% (or 100%, or 65%, or whatever) of people in a given society agree with you that verbally abusing a kid with disabilities is morally unacceptable. But I am certain that several people who agree with you on that have, in fact, verbally abused kids---maybe some with developmental disabilities---when they were kids. Is any of us free of what you would label morally unacceptable behavior? In other words, let he who is without sin cast the first stone.
But the larger point you may be missing is that you are constructing a binary of morally acceptable/unacceptable behavior and assuming that there are clear lines between one and the other, when in fact there is a continuum. And when there is a continuum, there is NEVER mass agreement on what is "okay" and what "isn't okay". There is no clear line.
So, according to you and some on here, Bobby Hull's actions are morally unacceptable and thus we should castigate him. But then what a Hall of Famer who did one incident of spousal abuse but otherwise has a clean, upstanding record? Then, what about another Hall of Famer who didn't sympathize with Hitler or his his wife, but abandoned his kids? What about another who did none of the preceding things, but committed a robbery when he was 17? What about another who did none of the above but got his high school girlfriend pregnant and pushed her into having an abortion? What about another who spilt some milk once at age 12?
What I'm saying is, the line between 'absolutely okay" and "not okay whatsoever" isn't as certain as you think. Likewise, the great divide between hockey players of great reputation and ones of dark reputation is not as clear as you think.
Which brings me to my next point...
