Nowadays, all insults and curses are sexist. There seems to be a problem here. If an insult is to be directed at someone, it should be directed at their behavior and character. It is unacceptable to insult their race, faith, physical appearance, sexual orientation, or gender.
An athlete's entire life shouldn't be affected by the insult. That athlete will likely become a worse, more aggressive person after that punishment.
punishment of words ends up sending them underground, where behaviours and resentment build with "like minds". People should say what they want, and then we can discuss it.
