Lets examine the type of man who unironically listens to Linkin Park, and not for the meme value of it like was popular a decade ago or so.

First what really is Linkin Park? It was popular in the early 2000s (big red flag there honestly). It was essentially an amalgamation of all of the worst music trends of that time, and I'd even go as far as to say Linkin Park is one of the first examples of music being what I'd call engineered slop meant to appeal to the masses at the moment it came out.

A man who unironically listens to Linkin Park is probably a millennial, possibly on the older end of millennial, and is possibly a manchild trying to relive nostalgia stuck in a past era and unable to fully grow past that. If he's too young to have any nostalgic memory of it in the early 2000's that raises even more questions honestly because how do you fall in love with slop music AFTER the era when the slop music was popular? It already wasn't made to be good then, and the music of that era was a fad that died off (thankfully) shortly thereafter so that's even more questionable than the manchild possibility.

I have no problem with anyone getting the ick over a man liking Linkin Park, that's 100% justified in my book.
