well the minmatar and caldari are neutral towards each other i dont see why some caldari here and there wouldnt support minmatar

The Elders (the true mind behind the minmatar) don't live in the republic. They've given up on it. They live out in nullsec among the thukker.

While almost 1/3rd of the minmatar population is still enslaved, more of the minmatar live among the nomadic thukker tribes than in the federation or republic.

That is entirely up to your interpretation. For me personally? I don't care much about the minmatar as I'm more interested in seeing a strong, independent and self-determining caldari people (I fall under the patriotic caldari). The liberals (largely ishukone, but a few other corps are involved) spend a lot of time courting the republic, believing that they're capable of nurturing a strong client / customer relationship in the future (they might even *gasp* become friends). The practicals are largely only concerned with the short term and are entirely willing to play arms dealer to both the amarr and the minmatar, as long as it makes them a profit.

So while the republic 'represents' the minmatar... It depends a lot on gallente aid, to the point where it's almost a sockpuppet / agent of the federation. I will give credit to Meleatu shakor (I know I spelled that wrong) for telling the federation to **** right off after karin midular (previous leader of the republic) was assassinated... by gallenteans.

The gallente are slowly annexing more and more of the republic every day.

You are a mercenary. If the republic is paying you for your services that's entirely up to you. In fact it could be better for you if you weakened the federation as you'd stand to profit more from defense contracts the matari put up.

Minmatar can't let go of the past, therefore screw them.
