Philosophy belongs in school, but I think it belongs in a specific level of school. If you don't have sufficient knowledge gained by years of compounded knowledge, you end up blowing hot unsubstantiated air. Its stinks because people who are interested in philosophy aren't really interested in philosophy, but again just like to blow hot air. I am glad to say that alot of people who comment on philosphyforum are genuinely interested in philosophy so its really refreshing.
But I am very interested in your second question, How do you get a class interested in listening to rants about such topics? Gimmicks? that's it? Gimmicks.
There are a few things to keep in mind.
Keep in mind that you are dealing with a group of people that do not share your affinity for philosophy and that type of abstract thought. They would rather do anything except that. You are dealing with a disinterested crowd.
Keep in mind that you are also dealing with people who have their own particular views, though they may be wrong. You are dealing with a stubborn crowd as well.
Also keep in mind that when you speak in an advanced way and understand things in a more advanced way, others will display a series of emotions in which may resemble disdain or jealousy and will see your comments and even your very embodiment as a person as a preacher preaching at a pulpit. No one likes to be preached to in an unwelcome way. So you are also dealing with a hostile crowd.
So how do you deal with a disinterested, stubborn, and hostile crowd?
Isolate the one feature that you feel the class is. Say the class is click-ish, that is, there is a person or group of alpha students who possess more popularity than you. Appeal to these alpha students with a topic that may be beneficial or interesting to them. Some may say that appealing to these types of people is ridiculous, but keep in mind it is they who possess the power and you who does not. You cannot break that rule? but you can bend it. If you cannot find a subject within the realm of philosophy, link a topic with something everybody would want to listen to. Use gimmicks like, money, sex, cars, power, etc. They will listen.
When you convey your ideas once you have their partial attention, remember that they are stubborn, disinterested, and hostile. Do not preach, they will become hostile. Do not be to complex, they will become disinterested. Do not overly insist on an idea or talk "matter of fact", they will be stubborn.
Be calm, relative, and personable and people will listen. However, the more favor you have with alpha students, the more you can display a more resilient philosophy.
If you possess that power yourself, you can talk until the cows come home and they have to listen to some extent and they'll call you "cool" at the end of the day.
