In the United States, at least, the terms “fascist” and “nazi” have entirely lost their meanings, due to over-use and abuse by American leftists: all caucasians are “racists” and “fascists”, Republicans and NRA members are “nazis”, and Donald Trump (bless his soul ;>) is “Hitler”. And who do we see actually promoting policies that would make real fascists proud? Our very own Democrat party...
But once you recognize that our leftists are projecting their own behavior the terms become relevant again.
