You're implying that having served in the military automatically makes you patriotic

If you volunteer to go to war to defend your country, it's probably a safe bet you care about your country.

you can find examples of never-Trumpers who were in the US military.

The problem is you're forgetting that different people have different ideas of what their country stands for. Some people think it's about 'tolerance and diversity' or other lefty ideals, and are willing to fight for them.

So an appeal to "military experience" isn't sufficient to say that in all cases you'll be more patriotic than any non-military person.

No, but it's fair assumption that the keyboard warrior probably isn't in a position to question a war veteran's patriotism. Because WTF have you done for this country that gives you the authority to call me unpatriotic?

And let's get real here - the reason I'm being attacked here is because of my criticism of neo-nazis. If you think that makes me unpatriotic then with all due respect I'm afraid you're fucked in the head.
