WHAT IS 'POST PUNK'? ITS A SHIT MEAN-NOTHING TAGLINE

Looking around Youtube in my idle hours looking at videos and listening to music I have been struck by the amount of people who are determined to keep pushing the label 'Post Punk' onto bands.
I can only assume that the people who use this meaningless term are either youngsters who were not around for the early bands, or they are the type who likes to keep his/her record collection in a certain order.
It bugs me because I see these people decide what is and what isnt Punk based on nothing more than either its year of release, or the records speed, if it was made after 78 and isnt played in the speeded up 1.2.3.4 style then it isnt Punk to them. Ive even had someone agrue with me saying Devo's 'Mongoloid/Jocko Homo' single was a 'post punk' single, even though it was recorded in ;ate 75 and released in the U.S in 77, they may of became an Electro pop band but they nailed the colours to the Punk flag when it forst appeared.
the same goes for bands like Television, they are also 'Post Punk' according to these young revisionists.
Their idea of 'Post Punk' seems to start in 1978/79 and includes every band that dont play sub-Ramones music, they dont understand that punk was supposed to be about a return to the simplistic Rock'n'Roll of the past, the stuff they grew up with on the radio. To these revisionists you can only be a Punk band if you sing about Anarchy, being working class or wanting a riot.
They judge Post Punk as roughly starting when the music press got bored of it and went looking for the next 'thing' (while thinking that the music mags ignoring punk was a sign that the last person had left the Punk room and turned off the lights, as if all punk related stuff just stopped one day), the silly sods dont think about how bands like Crass, Discgarge and the Exploited were out selling the bands who were top of the pop charts at the same time (but were not added to the pop charts because Indie labels had different distribution outlets, except a few labels).
Punk, from 78/79 to the early and mid 1980's was selling more records, and were putting on gigs in bigger halls that they could ever imagine in 1977, the Punk scene was at its healthiest at a time when the music press were trying their best to ignore it and declare it dead.
Next time you are on you tube and you see someone use the term 'Post Punk', tell them that they are know-nothing idiots who need to really look into musical history instead of just buying the same old music mag anniversary Punk issues that come out every five years (that all ignore bands that kept the scene going after 78/79), open their ears to the musical diversity that made early Punk so interesting. stop trying to be such arrogant know-alls about a scene that happened when they were in nappies.
And lastly, listen to the music and be inspired by it, fair enough, but stylistically, make something that you can claim is all your own, instead of just dressing up like someones Dad did 30 years ago.
