A great piece about how making assumptions about a culture and way of living or for that matter a person or a personality can be more damaging than anything in the world.
Remember that people don't exist of stereotypes and every person is a person in their own right.
Don't hurt people. Take a step back and question yourself if you might be part of the problem, even if you didn't think you were originally. Be honest to yourself. Have you possibly hurt people in the past with comments like this or attitudes which might have lessened the authenticity of one person?
Remember that every person is a person in their own right. They might conform to some stereotypes but people ARE NO stereotypes. People are people no matter gender, sexuality, colour or mental capacity. Everyone is a person in their own right and should not be made to feel less like the unique person they are just because they don't confirm to the stereotypes you think they should.
Also in the same thought is my own post from a while ago:
Gay men and how I like them best
Where I talk about stereotypes in m/m romance and assumptions some people have about gay men.
