true but at the time their images were not tainted by controversial opinions that defied the common establishment.
to use a rather common but inexact analogy, i can assure you that uncle laver wouldnt have a court named after him if he had been pro-nazi, regardless of how many Grand Slams he would have won.
I'm not sure about "controversial opinion" because she'll probably get an equal number of supporters as she does detractors – that's why it hasn't been passed as law yet. It may be a "controversial" in NYC but not so much in Texas; maybe yes in America but not so much in Asia. I'm certain if Rod Laver came out and opposed Margaret Court's opinions, you'd have a lot conservatives yelling for his name to be removed from his stadium.
I believe you have to look at Court and her age, upbringing… etc. It's not uncommon to have this opinion for someone in her age bracket.
