I used to be that guy. Then I somehow badly over-corrected and became the "everybody else hates this so I like it" guy.

Blood, soil, and a needle in both.

for me there can be at least 6 punk bands

Of course you watch Portlandia.

Of course you don't watch Portlandia.

Does that make it worse?

No.

Look at some obscure European bands ..... The Kids .... there are loads of decent French , Belgian , German punk bands that were pretty much unknown in the UK , its a shame as some were as good as any we had . Just generally look on Youtube or something like that , worth a search and there's plenty to like ... I'm afraid we in the UK at that time were a bit snobby about punk , thinking ours was the only or best punk . There was loads equally as good as ours .

Riverboat Gamblers were pretty good when I saw them a while back

I highly recommend Rancid's Life Won't Wait despite the amount of hate that band gets from people.

Hot Water Music's Caution is also a great album

Yo I love Hot Water Music

That's def an underrated Rancid album too for sure
