So, if someone asks me, "Are you playing golf this weekend?" and I answer, "Only if you are," I'm demanding that they play golf?
If someone says, "Are you going to the beach next week," and I answer, "Only if I can find someone else to drive" am I demanding that someone drive me?
If someone says, "Do you want to go for a walk later," and I say, "Only if it's sunny," am I demanding that the rain to stop?
Saying that you will only do something if certain conditions are met is not inherently a demand that the conditions be met. It's simply stating that, should the conditions not be met, you won't do that thing.
