It's not really that bad although mowing your lawn twice a week is a bit obsessive and he does have way too much junk in his yard, but having a unique looking house is actually not bad and it doesn't look like a junkyard from the set of Sanford & Son.

My only concern would be if his kitsch is collecting water that mosquitoes could breed in.  It's a bit tacky and I hate my HOA too, but they seem to ignore a lot of violations unless they're upset with certain people.

The sign is horrible though.   I would not like it in my neighborhood.   Political signs during election season seem acceptable to me even if I disagree with them, but he's just being obnoxious now but I guess he feels like he's been pushed too far.

The flag is tacky and kitschy but it's acceptable in my opinion.  And his yard is well maintained.  Hopefully those jugs aren't breeding grounds for mosquitoes.
