Words are often miss used.
www.thesaurus.com/browse/hostileI find it very hard to imaging any of the red words in the link happening in tournaments and if it did, why was that person not reported or asked to leave. It's not the sex, it's one individual vs another. Does the word some mean 99% or is it 1% of the tournament players. Numbers are clearer and more concise then words that tend to exaggerate beyond control. That's the assumptions pumping our imagination and then we cannot let go the thoughts. It drags on and on. Quoting after quoting to really rub it in.
Many schools now have chess classes or chess clubs. The drop outs happen most often when a student wants to play more then learn. Some have as an excuse their best friends are playing outside. So the challenge is best friends vs chess opponents. Best friends wins. Bye, bye chess opponents.
Players of all ages need to stop assuming and complaining. Honesty is very important. It's hard enough to sit at a table that is already occupied by strangers. Imagine being forced to sit in front of a person that you don't want to sit with. Maybe it feels like it cuts the air out of your lungs. So you have to resign because of the body odor or the breath or the words they say or the way they look at you or simply because of your own imagination that's sitting in the gutter.
There will always be discomfort in sitting in front of others. If a person cannot overcome this discomfort, then tournament chess is probably not made for them. All players need to resolve their differences and really wonder if they are made for the challenges that they must face. Not everyone is made to interact with every one. That's why we pick who we go out with or the job environments we work in or if we want to be part of a team or sport.
Are there still boy schools or girl schools? If there are, then this problem will be here for centuries to come. It seems unfixable because it starts when we are born and we impact our mind set over generations to come.
