The body of the government is supported by the people. Like, think of it this way. If I go to your house, claim it as my own, then sell it to other people. Is it your house or the other people's house? The other people bought the house knowing the unresolved claims against ownership and bought it anyway. Are they complicit in stealing the house? What if the house wasn't yours but technically your great grandparents but you'd still live there if it wasn't for those people who stole or the supporters of the thieves.

Just being given a vote as a minority doesn't mean their voice has been heard. You can see this sort of bias in Australian prisons: "Aboriginal and Torres Strait Islander prisoners accounted for 32% of all prisoners." They are disproportionally imprisoned and it's clear that systemic racism has put them in this position. So just getting a vote doesn't matter when there are more people who hate your race of people than the population of your race able to vote. It means you'll never gain anything in the system because racists will keep you down. Don't support systemic racism.
