Disrespectful to who? The soldiers who fought for our freedom 70 years ago? I don't think anyone is currently protesting against the USA of 1945, and I can't really think of any time more recently where the US needed to defend its freedoms. Most of the soldiers overseas currently shouldn't have even left in the first place and definitely should be home by now. If anything, it's the country itself disrespecting them by sending them off to die, get horribly injured, and suffer terrible mental illnesses.

Disrespectful towards the current politicians? Yeah, fuck 'em. I didn't even vote for most of them and now they're busy trying to take away the freedoms that the soldiers who are supposedly being disrespected fought for so long ago.

Disrespectful towards the country? Good, blind nationalism is stupid and dangerous.

All in all, it's kind of a non-issue. I do find Trump's hypocrisy both hilarious and disgusting though. Protesting is apparently only okay when the protesters are threatening to murder all non-white, non-Christians (because that's literally what Nazism is).
