I understand that hesitancy. It is hard to have people think that we somehow endorse a person speaking disrespectfully about women, or that we endorse someone with no moral scruples. But if the intention of our decision to support either candidate is with the best interest of the common good in mind, then we need not shy away from what others may think. The common good is more important than our image. The good of the nation is more important than our feelings towards a particular person.
Sometimes forces bigger than us come into conflict. Such forces can overwhelm us, and our actions may seem insignificant in light of such great evil. Combating those forces will require a certain fierceness from us. It will require facing decisions that we would rather not face—ugly decisions that will test the content of our character and the principles for which we stand.
A soldier going into battle cannot choose not to fight. Choosing to escape the fight is not only dishonorable, but it serves no purpose in battle, nor in defending the lives of those he loves. No soldier wants to go out and kill as many people as he possibly can, and no soldier should want to. But the soldier must make that decision. He must reach down into that savage instinct to protect what is his own and overcome the enemy for the purpose of the common good, for the purpose of protecting the rights, liberties, and lives of those he loves.
The task of the citizen is harder than that of the soldier in one sense. That of the citizen requires more deliberation about what the common good is and how to achieve it.
