While elements of what you say are true, I think it's more about who the people are.
For example, Bob Kraft got plenty of grief over his involvement in these types of places, although he apparently did so with consent. He was on the news over it for months.
DeShaun Watson did it without consent sometimes, allegedly.
Those two are/were the faces of a franchise. They have a much higher profile than Tucker. After all, Tucker is a kicker.
If Tom Brady did it, what do you think the media would do?
There's also the idea that Kraft was the first owner and Watson was the first player to have to bear such allegations. So the "newness" aspect drove some of the media narrative IMO. It's similar to the first time someone like Ray Rice did what he did during the Me Too movement.
As for the punishment phase, Tucker was just waived by his team after they looked deeper into the allegations apparently. What else could a team do?
My point is: I think there are certainly some elements of race as an issue in America that are valid. And part of what you wrote above is true.
But it's not exactly an apples to apples comparison like you make it out to be.
Again, America is not perfect. I'm just not so sure this is a shining direct example of what you speak.
