No disagreement from me there, never been a fan of the Sex Pistols at all for numerous reasons that one included.
I'm an occasional fan of the odd punk band, and was certainly more into punk when I was in my teens, even with my small steps into the culture I saw some interesting sights. The most memorable being seeing Black Flag and Jerry Only down in england, my first real experience of how cookie cutter and tame most modern punks are.
These days there are pretty much 3 types of punks, when it comes to the fashion side of thing. Those, usually older, ones who keep to the original thrift store with maybe a little modification but really whatever you want ideal, then the second group based on Mr Vicious and the modified leather jackets, and then the third group, who don't modify anything, they buy the whole lot premade.
The second and third groups do have that very noticeable different mind set, but the end result is the vast majority of "punks" being almost identical, with only slightly variations in the shape of studs they bought or the colour of one of their mohawk spikes.
I've always ended up being an outcast of both punk and metal/crust (which is really trying to hard to be the new underground punk) circles simply because I aways refuse to wear the uniform they tout and like every band they say I should like.
