I think a lot of people think that, and they can be. all fandoms have a portion that are hard to get along with/toxic. it's important to remember that those portions are also often the minority. they're just usually the first ones you see. :/
depends on if you're drinking because you're super thirsty or if you're just trying to enjoy a cold beverage.
it's okay to judge whether or not you'll get along with someone after the first impression. a lot of times, your internal warnings are there for a reason.
