Why do people think my sexuality is a mental disorder and/or invalid?

People think that my sexuality is a mental disorder and/or invalid because they can't relate to it nor wrap their heads around same-sex attraction or not feeling any romantic feelings. People have a tendency to label what they don't understand as an illness or make believe.

People have all sorts of opinions, and ways of dealing with their own truths. They may be unwilling to accept your sexuality because it makes them uncomfortable, and they are unsure of what to do with that. They could equally have religious views which conflict with their understanding of your sexuality, and that too makes them unsure of how to respond to you. In any case, recognize that this is -their- issue, not yours. You are perfect the way you are.

I know that it can be hard to deal with. But some people simply just do not understand sexuality. It is not a mental disorder or invalid though. You are who you are.

Many fear the unknown, and because of their flawed attempted at understanding or trying to reconcile information...they're looking at it as if it were a disorder or not a valid thing. It may sound unusual, but...for those not familiar with the gender and orientation spectrum, it can cause confusion .

Because sexuality was labeled as a mental disorder in the past but had since been removed. However, times are changing right now but then there are still some people who were brought up with traditional values.

a common issue in societies throughout history is a response of hostility towards anyone outside of the cisgendered heterosexual norm. Unfortunately for many, this means an undeserved exclusion on the grounds of your 'atypical' identity. The idea that people of the LGBTQ+ community are 'invalids' or 'mentally disordered' is a construct created by a combination of fear, superstition, conflicts of faith (e.g religious interpretation), to name a few. Nobody is an invalid human being for having a specific identity trait, we are all human, its just unfortunate that many groups, including non-heterosexuals, have a long way to go before society will grant them status as their equals.

Some people don't understand certain sexuality, like people have told me I can't like both boys and girls because that's not normal, so depending on what you are, people may not understand and it makes them uncomfortable so they try to demean you and bring you down because when most people don't understand it's "wrong and you're crazy"

My honest and simple answer to this question would be because they're ignorant. Your sexuality is NOT a Mental Disorder in any type of way, shape, form or fashion. Sometimes people can't help who/what they fall for. Just like straight people can't help that they fall for the opposite sex. People that aren't straight shouldn't be treated any differently than people in the LGBTQ community. You can't be punished for what you feel in your heart.

Often times when people do not share a common sexual orientation, one will think the other odd due to a lack of consideration or thought. It could also tie in with religious and cultural beliefs and whatnot which makes them look down upon others.

Because people are biased and ignorant and don't understand that sexuality is a natural and permanent characteristic.
