I understand what you're trying to say, but it's not true or real in the sense that the counter-argument is entirely effective. Specifically, "When that thing you're worried about actually comes up, then we'll decide what to do." Saying, "We're still three steps from my issue but this thing that, in and of itself I have no problem with, can't happen because it might lead to the thing I have a problem with." is not a valid argument. To try and bring it back into focus, it's a real problem that this "one pic" isn't being shown. It's not a slippery slope conversation, because we're already at the thing I/we have a problem with. No need to argue the "this paves the way for worse things" because this is the worse thing! We're here!
