I am all for letting people decide. But I can also critique the decisions that people arrive at and choose not to ally myself with them if I disagree with their decisions. That the process is democratic does not demand that I automatically endorse the outcome of it.
The people of the state of Ohio may democratically vote to limit marriage to a rite between one man an one women, but that does not mean I have to agree with their action and refrain from criticizing it.
