Ex military is the sort of hyper jingoists one ought to avoid.
I steer clear of anything and anyone who has an ex-mil lineage. Their opinions are loaded with bias and will lead to an overall loss of the picture.
Ex-mil ought to be viewed as Military itself. Just because they formerly held ranks doesn't mean they have abandoned their zeal, core values, outlook or ideology.
I remember a talk show in Indian media (there is a YouTube video) where an Indian Ex-mil stated that China developed J-20 and Y-20 by "copying" others.
No evidences to back those claims but all I inferred from it was that he is still doing service for the country by bashing China.
I've seen more balanced views from Amateurs and Fanboys.
