Partly it's just the on-going decline in politics visible almost everywhere and the shameless appeal to the lowest common denominator by this current US administration in particular, folks.
It's like the American use of the word 'liberal' or 'socialist'. They tend to have no idea what these words and terms actually mean only what they have been perverted to mean in the US today.
Newspeak for the USA.......just as their uncritical supine media has become a US Pravda for our times.
It's also, IMO, about self re-inforcing, fostering and extending this idiotic quaisi-fascist 'with us or against us' garbage and risible nonsense.....
.....and no matter what the truth of the actual situation (for instance the undeniable truth of the approx 50/50 split in American opinions of those who bother to vote in the US) they just keep claiming come hell or high water that they and their values represent 'America' and 'Americans' - even though they are clearly actually a minority within the US.
Frankly I find this kind of crass unthinking stridency simply illustrates just how unsure of their case those making these claims actually are - and rightly so given their distinct lack of majority support.
But let them, obviously any sense in all of this passed them by long ago and it does give the rest of us a great big laugh seeing them attempting to slam non-Americans as 'un-American' here.......even if we do feel a tinge of embarrassment for them in their ignorance.
