Bad Religion and Minor Threat guitarist Brian Baker is currently engaged in a confusing feud with popcore band Bring Me The Horizon. Both Bad Religion and Bring Me The Horizon are currently playing at Spain’s Resurrection Fest.

Following Bad Religion’s own performance, Baker noticed a sign taped to a wall by Bring Me The Horizon.

The sign read: “These people are not to be stopped ever. They may not have a pass. They can escort who they want where they want with or without a pass.”

Baker immediately took offense, Instagramming the sign along with the caption “I’m going to stop these people every time I see them today and tell them how much their band sucks.

I’m going to stop these people every time I see them today and tell them how much their band sucks

Bring Me the Horizon guitarist Oliver Sykes and drummer Matt Nichols quickly retorted. Nichols commented on Instagram:

“Hahah I can’t imagine being as old as you are and still acting like a 14 year old girl, Nichols wrote. “Saw you at least 10 times and you didn’t bat an eye lid. You got bigger things to worry about nowadays anyway, like ya pension, or cold weather. Dickhead.”

Sykes added another retort, commenting, “Yeah we are not your enemy, winter is your enemy.”

Baker proceeded to issue the feud’s last known public statement. He posted the following in response to his original Instagram post.

It seems you’ve missed the point entirely. The issue here is entitlement. My post was a comment on your collective delusion that working local crew at a thirty band festival should be required to memorize your faces to spare you the indignity of breaking stride on the way to your backstage oasis or even worse, the humiliation of carrying credentials. Your literal display of arrogance (and the hilariously unrecognized irony within it) was what I was sharing with my followers. I honestly don’t know if your music is bad or good – it’s not for old people! I meant that you suck as humans. Sorry for the confusion.

Baker has been relatively active musically when not engaged in petty conflict with other musicians. He released two songs on Cold Heart 7 with Dag Nasty earlier this year, and last released an LP with Bad Religion in 2013 (True North).

Bring Me the Horizon, meanwhile, last released new music on 2015’s critically acclaimed LP That’s The Spirit. They are still touring in support of that album, and have yet to announce plans for a new release.
