Here is how I see it.
Act your age
This one you might as well throw out on it's face. People can't even "act their age" outside of the sports arena.
Don’t live your life vicariously through your children.
I can agree with that, but it sounds like an excuse for parents to not be invested in their kids path in sports. Parents are invested in their academic path, so why should sports be any different? I never cared about playing the sports that my kids play, but I'm invested in their journey.
Let your children talk to the coach instead of you doing it for them.
I can agree with this as well, but there are issues that require parent coach conversations IMO.
Stay in your own lane.
No coaching or officiating from the sidelines.........so what are fans supposed to do, not have an opinion and not discuss those opinions with other fans??? How about coached and refs not be so sensitive??? BTW, I know a couple of refs personally. They let that ish roll off their backs.
Remember, participating in a high school sport is not about getting a college scholarship.
It may not be for some kids, but it may be for other kids and I don't see anything wrong with that. There are kids that work year round at their sport(s) and the demands of many of the programs that I've seen would give one the expectation that college might be an option after high school. Everyone isn't going to go FBS, but FCS, Division II, and NAIA give scholarships and a good high school player can make it to those levels for sure.
Make sure your children know you love watching them play.
I agree with that.
Purchasing a ticket to a high school athletic event does not give you the right to be rude, disrespectful or verbally abusive.
I agree with that as well, but it's sports and sports is a competition. Competition is HIGHLY emotional so to expect people to not get out of hand from time to time is not realistic. We are expecting people to not be human. As long as they aren't threatening or physically harming anyone I say that it's all part of the game. And if you want to talk about being rude, disrespectful or verbally abusive you might want to talk to some of these coaches. They can be some of the most rude, disrespectful, and verbally abusive people that you will ever meet.
