Secret approval means supporting something privately, without openly expressing it. It's like liking a meme but not sharing it because you're not sure if your friends will get it 😅. It's a form of unspoken endorsement, where you agree with something but keep it to yourself. Maybe you don't want to cause conflict, or perhaps you're simply not ready to publicly commit to a position. It's a quieter, more personal form of agreement. It differs from 'connivance' in that it doesn't necessarily involve wrongdoing.
