"I'm only into white guys"

You'll probably think I've been living under a rock after I write this because apparently this is a huge issue in the gay community, but I'm going to anyway because Its really upsetting to me.Basically, I had no idea whatsoever racial preferences existed in dating and hook up culture till about 3 months ago when I started attending college, and I was so completely dumbfounded when I did discover it to the point I didn't believe it at first.A little bit about my background: Growing up, I didn't realize it till now, but I guess I went to what many would consider a "diverse" high school. I'm white, but I was around people of all different backgrounds and ethnicities. Being a hormonal gay 16 year old, I found a lot of dudes attractive, and had plenty of crushes. Sometimes they were white, sometimes they were black, sometimes they were asian, arab, latino, etc. Its not that I didn't notice race, it was more like it wasn't unusual or weird tome to find someone of another race attractive. I never thought anything of it, and if I ever did, it just seemed logical. Like I thought there was scientific explanation out there that said something like we like other races because in our subconscious it represented genetic diversity aka healthy offspring. There were also plenty of interracial couples at my school so I never thought I was standing or special in any way to feel this way.Fast forward to college - through grindr and meeting other gay guys, I begin to discover a lot of guys, whether they're white or non-white, only have a thing for white guys.Now I know this isn't the case for everyone, or even the majority of guys. There's always exceptions/generalizations blah blah blah. But after meeting a significant amount of guys who "have only ever found white guys attractive" and seeing a lot of grindr posts about "no blacks/asians/latinos" I'm starting to see there's a weird phenomenon about how the gay community views "white guys", and it's pretty much we put them on a pedestal.This really upsets me, and I'm not even a minority, just because I feel this is more social driven/underexposure then it is legitimate "preference". I'm really frustrated at the fact that there are a lot of white guys that act almost snobbish and elitist when they express they have no interest in minorities. The almost "sorry but no sorry attitude." Sure, I understand not being attracted to someone. I'm not attracted to every minority guy in the same way im not attracted to every white guy. But the difference is, is that I'm not attracted to them simply because they are unattractive as a mate to me, not because I "prefer" a race. And it doesn't stop me from finding plenty of other minority guys attractive.What baffles me even more is when a minority guy tells me that they are only attracted to whites. Like....what? Wouldn't you know first hand what its like to experience racism? So then why would then inflict said racism onto other minorities, and what right do you have to be pissed off when a white guy tells you they're not attracted to you?I understand this is a touchy subject and I didn't mean to step on any toes but I had to get this out here because I'm really confused and quite honestly angry at how im just learning about all of this.
