<human>: Can you summarize the given text in a few sentences?

So i'm in highschool on the debate squad. And my debate squad is pretty hardcore. We travel to tournaments all over the country and spend probably about 40 hours a week working and researching debate stuff. Good partners are a hot commodity, and over the past summer I've been able to land myself a spot on an international debate squad too. So i consider myself to be pretty good. My coach, however, decided not to send me out to the first tournament of the year, this huge tournament in Texas that all the scouts go to. She justifies it with the fact that I'd be riding in the van (which is about a day's drive from where I live) and everyone else would buy a plane ticket and get there earlier. She said in an email that she sent after school before the long weekend, that coming home late would put me at a disadvantage because I'd have to catch up on homework. When I read this Friday night, I was pretty mad. I'm the only one on the squad not going. So I sent her an email asking her if it really was a money issue. I told her that I was disappointed that I could not attend the tournament and if she thought that I would be able to attend any other tournaments this year. I admit, the email was pretty sassy, but I wanted to get the point across that I was really mad and I could pull out and do my international stuff at any time. So now this is getting a little long, but I promise I'll get to my point soon. Today was the first day I had school, and I was immediately pulled into the principal's office to talk about this. I thought it was a little harsh but I told her how I felt and all of a sudden, the principal starts telling me that she saw my email and thought I should apologize to my coach for being disrespectful. Reddit, who's right? Because I feel really hurt for being put on the back-burner. I devoted my entire freshman, sophomore, and now junior year to this activity, and all she's done is exclude me. I just think I'm caught up in the moment, so I'd appreciate any input you have:)
<bot>: High school debate coach benches best debater for the biggest tournament of the year. Benched debater sends (possibly disrespectful) accusatory email and gets called in by the principal. Ref needed.
