In the first question, as millennials, it is ideal if you create a blog, where students can interact to your opinion and can voice out their feedback also.
For the second, don't go after the controversial issue, much more when you are writing it over the internet, you will be feasted with ants and rats. Just go with your personal thoughts and research about it so people won't see you as an attention-catcher only. If your research is reliable, they will respect you for that. Everyone has its own freedom of speech and it is in the code of professional ethics. Voice your own opinion and be realistic, someone whom others could believe in.
Third, just start with the persons whom you are closer too. Hear their opinions and discuss it with them. Listen and accept their feedbacks, and if they say that you should spread it publicly then you should.
Last, don't argue with a particular view point. Some will hate you with that as they think that you are stomping on their ideals, you will be the talk of the people. Just go with your own opinion. Accept different answers, respect them and judge each replies if it is accurate or not.
Your opinion must be heard. Herald it.
Hope that answers your question.
