More than crap talking I am stating what everyone should of been saying to him.
You weren't the first to dissuade him or question his decision. That said, differing opinions are fine; even stern warnings are welcome. The problem was your tone.
We get it, your username implies that you'll be sarcastic, but I'm not inclined to give everything a pass just because there's a preface. This isn't Reddit where we go mainly for laughs, where joke accounts are aplenty. This is a forum to receive support and to get information for life-changing surgeries.
If you want to give sound advice, go for it. Your last reply was great, I commend its thoughtfulness. It beckons careful reading, consideration, and respect. The previous replies just conjured knee-jerk reactions. If you want to have fun, I suggest Off Topic.
