does anyone else hate stereotypes?

i think it is ruining peoples chances to get to know individuals better. and most of all ruining peoples chances to make friends, or worse it can ruin friendships. i think this is really bad at the high school level. for example apparently all boys are perverts, all girls are sluts, all boys are immature, or all girls are weak. i don't think we should look at people and make assumptions based on gender. we should look at them as individuals. they are their own person. they are not something stereotypical because of their gender or because of the clothes they wear, their height or weight. i think the most annoying one for me is the gender. its putting half of the population into one group. when obviously not everyone is like that. i think these stereotypes exist because people may not want to take the time to get to know the person.
