Kids need freedom! It is proven that physical activity increases the brain's activity. It also shows that it works better when learning after recess. Plus, in many middle schools worldwide, gym class is not an everyday thing. At my middle school, it is every day for 1 semester in both 7th and 8th grade (6th grade is in a different building and has recess). So I'd have a full semester without any physical activity (minus walking to/from classes). It is also proven to curb the side affects of ADHD.
Better taste than school food. Yes, obesity is a massive problem in the USA (and worldwide). Yes, fast food is unhealthy. Yes, there are definitely cons to having fast food in schools. I'm saying that it should be in schools because kids prefer it, and, depending on the item, is also healthy. I'm not a supporter of having a McDonald's in every high school in America. I do support places like Subway, Jimmy John's and other rather healthy places. Basically, few to no McDonald's (and it wouldn't exactly be popular anyway, at least at my school. I personally hate McDonald's), But I do support local fast food places as well as regular chains (in my area, Wendy's, White Castle, Donatos, Cane's, etc.).
Public School is Inferior Public school has one notable pro over school. That is social interaction. However, that can very easily be fufilled by clubs/sports. Everything else points toward homeschooling. For example, homeschooling is cheaper. I saw one thing that said public schools pay around $9,000-$10,000 per pupil. Homeschooling? About $500-$600 per pupil. And it has been proven that homeschooled students do better on standardized tests than public school students. For about 5% of the cost. There's also no bullying with homeschooling. Students are forced to learn one way by the school system. That student may be better taught in a different way.
Keeps the school safe. Teachers should be allowed to have guns, but only if they pass some requirements. For example, the teachers should pass a regular concealed carry class in their state. If the school building is divided between, say, Indiana and Ohio, the teachers in that school building must pass the stricter concealed-carry rule in those 2 states. There should be a concealed-carry class for teachers in states that are open carry as well.
The guns should not be a certain type, as in all teachers shouldn't have to carry a Glock pistol if they'd rather have a Smith and Wesson or something else. The teachers shouldn't have rifles. They should be pistols, and the magazines should comply to state standards.
Don't forget this phrase is true: "The only way to stop a bad guy with a gun is a good guy with a gun."
