Give him a break....
Looking at his previous posts, I don't think he is a troll, just someone who wants to join the mob and is rightly a little concerned about the general feeling of serving personnel.
ML I left a year ago so am a little out of touch. Things changed a lot in my 13 years, but then again when I joined you had people telling you ' it's not the same as when I joined'
If you really want to do it, then do it. Get through training then make the most of it.
Best wishes for the future
