I know both Alix and April, the women's beach volleyball gold medalist, both put their hands over their hearts before matches. I saw several swimmers do the same and some had tears in their eyes when the national anthem played.
Some lady who won silver in track and field...She did a "protest" during the medal ceremony...That was annoying...
There were not many "protests" by US athletes...Not really...Many conservative writers speculated that the Tokyo Olympics will be very "politically correct" because athletes will constantly engage in "protests"...I do not think that is what happened...
Both US men and women teams won the gold medal in basketball...I am sure that many team members were BLM supporters...But, no male or female basketball player engaged in "protest" during medal ceremony...
I have seen Alix and April play in person...In the past...They were playing at the beach volleyball tournaments...Admission to beach volleyball tournaments are free...Usually...
