So it all boils down to "No True Scotsman"? How about I offer you an alternative:

We don't try to guess why you bought what you bought, or why you need to so actively rationalize it, and you stop assuming that those stickers are something other than "Please don't key this car" signs. Less dramatically some of them are also "I bought this before the guy started throwing celebratory HiterGruß on stage and carving up important parts of the government for nonexistent savings."

Which... for people outside of your bubble is something important.
