I am not getting along well with my colleague. Should I resign or stay on? Advice!

I went back to school this term to pursue a CS certificate in order to hone my software engineering skills. I decided to take part in the student government association by applying for a senator position. I got interviewed by the vice president and speaker of the senate (both females), and I was nominated for confirmation in the senate. During my nomination, I noticed the executive board (President, VP, Directors, Attorney General, Solicitor General, Treasurer) and senators except one gentleman were all females. I was happy to work with them and fortunately, I got confirmed as a senator. I have barely spent more than one week, but I have begun to resent all my female colleagues. Particularly, the president and vice president are not approachable, bossy, and a little bit unprofessional even during our formal sessions. In the Senate, since we are just 3 boys and 15 females, it's hard for me to work with them to draft legislation. Plus, there is a lot of conflict of interest that I noticed among them, yet they don't abstain or disclose it upfront that they are affiliated or will benefit from a particular group if we are voting on legislation. They are also full of bias - they didn't nominate and voted any boy for senate leadership. We have an internal election for Chair of Appropriations Committee tomorrow, I can nominate myself. But I am thinking these ladies will not vote for me even though i meet the requirements. In my old school, I was part of the SGA, and I got along with all the females perfectly. Our boss was a woman, so i don't hate women. These ladies are just different. How can they use Beyonce pictures as a profile photo for our Senate internal chat? I couldn't complain or even raise my objection. There is a lot of stuff that's not going well, but I just don't talk so they won't label me a sexist. Lastly, all our SGA members are all Blacks, which to me isn't representative of the whole student body. I feel they are biased with their initiatives even though i myself I am black but not from America. How can I voice my concerns without being accused of sexism, misogyny, or patriarchy? Should I resign or stay on? I have a lot of initiatives I want to work on to help students.
