For those of you not familiar with the "going in" term, it comes from online videos where people will "go in" on a subject and basically rant about it and explain what they dislike about said topic. My topic that I'm going in on today: Nostalgia Elitist. You know what I'm talking about, those people who no matter how much factual proof you provide them with they will still believe their old ways are superior. Now I'm not talking about people who like old things (such as cars for example) I'm talking about people who for whatever reason stick to certain things and then have to be a jackass about it and tell you how their way is better. Let me give you guys a couple of examples.
Example one: CD vs Vinyl

(please note I specifically am saying CDs, not MP3s where sound quality is dramatically lost)
I'm not knocking vinyl here, if you have a badass vinyl collection then more power to you, I'd definitely want to check it out and I agree they are much more of a collector's item than CDs. But don't bring that "Vinyls have a better sound quality" or "Vinyl captures sound better than CDs" bullshit up in here. If you prefer the sound of vinyl compared to a CD then cool, more power to you, but just know that the "fuller" sound you are getting is due to ineffective recording techniques and you are picking up on a lot of distortion/surface noise/ect. Not to say any of that doesn't sound fine, but don't try to tell me it is actually higher quality, you are confusing a defection on vinyl's part as a superior trait. Common sense should tell you CDs have a higher quality sound in that a CD has a FUCKING 70 YEAR technological advantage on vinyl. You would think that a laser guided mechanism would have a little more accuracy than a needle in a plastic groove, but nostalgia elitist don't use common sense or logic, they go by "feel." They know that their vinyls are better sounding because they just know, they feel it; facts, technology, and science be damned.
Example two: Old school BMX bikes vs new
You non-bmxers won't understand this, but it applies to about half of the posters on this site so why not. The bike I had before I quit riding weighed 45+ pounds-it had a 45 tooth sprocket, a motorcycle chain, ultra thick 4130 chromoly tubing, pegs that weighed a pound a piece, triple walled rims, hell I might as well have poured some concrete in there to build up my cred (heavy bikes were the trend, the heavier the better was the idea back then). My current bike weighs half that, if not less-23 tooth sprocket, normal chain, thin tubing, plastic pegs, light as hell rims, ect. There are a ton of old school bmxers who refuse to go with the light bikes even though the technological advances in metal working/polymers have provided not only lighter parts, but stronger. My old bike used to bend and break parts all the time, I rarely break parts on my new bike. Not to mention a lighter bike makes riding more comfortable and you don't get tired because it doesn't feel like you are jumping a tank.
There are other things I could go in on, but that is enough ranting for now. I'd like to see some topics you other posters want to go in on, I could forsee some hilarious topics.
