sure there are a lot of people unsuited for military service that doesn't justify disparaging them for not serving.RetiredGySgt And I served for 10 years. And am over 14 years into my second military career.
But if somebody has highly biased political views (to either side), they likely do not belong in the military.
Bad attitude, likely to be a major problem as they will not "play well with others", but instead want to argue and fight about almost anything.
I literally first went to MCRD during President Reagan's first term. And have served under every President since then. Never mattered to me if they had an R or D after their name. If somebody thinks that is more important than serving their country, then they are likely better off never serving.
