Is government spying on US citizens OK?

In my honest opinion the government has no business spying on it’s own citizens. I know there’s a need to protect us from terrorists that wish to destroy our way of life. Our president has said that we need to compromise our freedom somewhat in the name of preserving freedom. Is that possible? How is losing freedom preserving it? At what point does the end not justify the means? Can we really believe that they will never listen to private calls? Are they listening to every ones calls now? I believe that they are. Please don’t call me a conspiracy theorist. For why else would they need that monstrous new warehouse for data? Just meta data? I don’t think so. Our calls are being recorded and listened to. To some extent at least. Are you ok with this?
