Hey! I'm left-handed and it's...okay...I guess.
If anything being left-handed forces you to be more useful with your right-hand than a right-handed person would be with their left-hand. Silver linings?
On-topic, keep complaining, make your voice heard and keep thinking and talking about it. It expands the way you think about everything, and yes, definitely start an organization if you feel that would help. At my college there are organizations for just about every minority group, if that's not already a thing at Boulder (...probably a less diverse place) then I would recommend it. It's an empowering thing, especially if you're the one founding the organization.
