This isn't a scandal. He didn't disparage the soldiers or the veterans. Some people come back in stronger shape than others. Some see things that don't faze them. Others are shattered and permanently destroyed. I have-or had, better yet, one relative who went to Iraq. He was married to my older second cousin and I don't think I ever met him, though it was a big deal when he got shipped over. From what I later heard, he came back completely fine (no injuries, no obvious signs of PTSD, and no diagnoses). Yet, before I ever even got a chance to meet this guy, the two ended up divorcing because they grew apart and I haven't heard anything about him or for that matter, even his wife who was my cousin, in several years.
You don't have to be "strong" to be a hero. You can be an American war hero without having to put on this false display of normality. Trump just happened to note that many people who are suffering from PTSD due to a terrible war, built around a lie created by the brother of one of Trump's Republican rivals and supported by then Senator Clinton, can't handle it. If they were handling the PTSD well, they wouldn't have been forced to commit suicide as their only escape now would they?
Again nice try, but you all are better off making another eleven threads about the taxes. At least there is some smoke there (not the raging brush fire of the Clinton emails, but whatever). Now you guys really are just looking for a scandal.
I don't think anyone is saying that it's a scandal, as such. But it's certainly a remark that could be off-putting to one of Trump's strongest constituencies, and as such it was ill-advised. Of course, Trump saying ill-advised things isn't really news.
