After reviewing this entire thread, I can see why you hold the position you do: It is because you identify personally with this situation, and you see Warmbier, Jr. as your son, and yourself as Warmbier, Sr.
Your son is likely a fuck-up. You describe it in the quoted post. And, seriously, how could he avoid it? You are a person who spends hours on end on a gambling message board (25,000 posts) and calls people an "abortion," a "douche," and describes people's comments as "fucking dumb," just in this thread! Why do you think he ignores your advice? What an example you have been for 18 years!
Since your 18-year-old son isn't following your advice, it obviously hurts you, and you have rationalized the Warmbier's plight to be the same as your own, so you sympathize with them and defend them.
