people who have problems with how athletes react to losing are losers

So I'm watching the Australian open finals, and when the person loses she congratulates her opponent at the net and then walks back to her bench. She then smashes her racket before walking off into the locker room before returning for an interview. As soon as a I saw that I was like this better not be a story, low and behold I've seen like 10 posts about it in the tennis sub. Like Josh Allen said when people had a problem when his coach had a meltdown after losing, "show me someone who likes losing and I'll show you a loser." IMO, everyone who has a problem with how some these athletes react to losing have never played anything at a high enough level where it matters. Now im not saying you defend athletes who are blatantly disrespectful, there is a line that you cant cross, however, smashing a racket or a small reaction isn't that
