I don't know that I would necessarily extend any ill feeling towards the current AVMA towards SAVMA (though I do think the policies at your school seem a little unreasonable, that is the fault of your chapter, not SAVMA as a whole). SAVMA should be functioning to support clubs and student involvement. Things like SAVMA Symposium are networking opportunities, and your school chapter should be providing resources to help students attend. And I think students being involved in that kind of stuff is the only way we have any hope of changing things at the AVMA level in the future. It's not like you can have any say in all of the issues of accreditation and class sizes if you're not involved.
