Can you explain what is the meaning of the sentence?

Are the below sentences correct in a given situation.
To inform you is to inform the whole city. (For example I have a friend who doesn't keep secrecy, whenever I give him some secret info, he leaks them to others. So I tell him in fury mood, "to inform you is as to disclose the secret to all the people of the city")
To teach you is to teach a child. (It is very difficult for me to teach you. Because your learning abilities are as slow/poor as a child)
To convince Alex is to convince my wife. (In my day to day life, it is very difficult for me to convince my wife. Similarly I have a friend - Alex and it is as difficult to convince Alex as to convince my own wife)

1 and 2 are possible, though would sound contrived if you actually said them. 3 doesn't work for me.
