#1: I'm a big nerd. I like anime, tokusatsu, video games, making cheesy movies, new gadgets... but I'm not completely socially inept like most nerds. I usually can't stand most other nerds. Most of them never want to do anything other than whatever game or show or whatever they're currently obsessing over.
#2: I'm also gay, so that doesn't help either (my profile says "bi" because it just kept filtering out all women in my results and I'm just looking for friends). Not that it's something that really defines me. I'm not a "full time homo" as I call them. You know, the people who ALWAYS talk about being gay, move to gay neighborhoods, only have gay friends, only go gay bars... The kind even the stupidest and unobservant people know are gay. My sexual orientation is at the bottom of the list of defining characteristics.
Somewhat of an extension of that, it's the same thing with other gay guys as it is with other nerds. I usually can't stand them either! I'm not all feminine (but too nerdy to be masculine), I don't hang out in clubs, I don't sleep around like it's a competitive sport, I'm not into fashion, I find celebrity gossip offensive to humanity... you get the idea. That leaves me and the stereotype very little to talk about. I can usually blend well enough into a group of straight guys, but I am in every way the exact opposite of a frat boy. I don't like sports, drinking, drugs, naked women, or competitive alpha male asshole-ism. And girls are fun, but I'm never "one of the girls" either, nor do I want to be. I can have long conversations with them, but when it comes to activities, the nerd in me ruins all compatibility.
Barrier #3: I'm such a friggin goodie-2-shoes. I don't drink, smoke, sleep around, or do drugs. I'm finished with school, so like the only social activity that is ever on the table is going out for drinks, hence the withering social life. Trying to find other people who don't do any of those 4 things, but aren't crazy and church-y is impossible! I'm not a buzz-kill either!
I hate how much people obsess over alcohol, smoking, drugs, and all that. It's a damn beverage, not an activity that requires an entire evening! Smoking and drugs are merely bad habits that severely ruin your health, not hilarious and adventurous alternative lifestyles. These things do not make you cool. Being Batman makes you cool.
