Not to insult you, but if you look from the perspective of the typical anti-gun person, they have no problem with the authorities having weapons. They just don't want them in the hands of the common rabble.
As an employee of the federal government, I doubt many people on the anti- side have any problem with you having a gun. You are there the protect and serve their interests, after all.
Now, should you leave the service of the liberal super-state, well, what business do you have with a gun, at that point? You are allowed a gun only to the extent that you are serving the interests of the state.
And further, bourgeois capital really sees the sort of person who chooses your career path as de facto expendable. If a few of you suffer blue on blue mishaps or PTSD related suicides, well… How much collateral damage is acceptable? All of it. As long as it happens far away and to people not from their social class, gun deaths are simply an abstraction to the antis.
i admire your courage and resolve to defend the Constitution, much as a I'm chagrined by the abuse of your service by our currently directionless leadership. Please come home safely.
