Our system, at times, doesn't let us vote to impede human rights. Gay marriage is now the law of the land, because the Supreme Court deemed there to be a right to it despite legislative efforts. The right to a fair trial isn't always popular, but we don't get to vote on it. The right of the KKK to march and speak isn't popular, but we don't get to vote on it.

Same with immigration - courts have blocked plenty of enforcement measures and violations of human rights like long-term detention of children. There's a reason "majority rules" isn't the only way we do things in the US and most other democracies.
