Straight

Straight, also known as heterosexual, is a sexual or romantic orientation.

People with Binary Genders
Some people with binary genders are straight. This means they are exclusively attracted to the "opposite" gender. Some break this mold by also being attracted to nonbinary people, but if they say they are straight, they are still straight. Some may find the term straight offensive, due to the opposite of straight outside of the context of sexualities being "bent", which has homophobic connotations.

MLW
Men who are exclusively attracted to women are straight. That being said, some may not be comfortable with the term due to the traditional opposite being "bent" which has homophobic connotations. An alternative label would be heterosexual / heteroromantic*

WLM
Women who are exclusively attracted to men are straight. That being said, some may not be comfortable with the term due to the traditional opposite being "bent" which has homophobic connotations. An alternative label would be heterosexual / heteroromantic*

Non-Binary People
Some nonbinary people wish to be refered to as straight. This can be for many reasons, such as not being nblnb, or having an aligned gender.

Masc. Aligned nblw / Fem. Aligned nblm
If a person with a non-binary gender feels an attachment to a certain gender that is incomplete (demigirl/demiboy/etc) and is attracted to the "opposite" gender in the traditional gender binary, they may describe themself as being straight or heterosexual. They do not have to describe themselves as straight, however, since they may consider the label to be misgendering to them.

Unaligned Non-Binary Persons**
If a non-binary person feels unaligned from masculinity or femininity and only feels attracted to people with a connection to either feeling, they can be straight. This means that if a person who was agender felt attracted to men and women, they could identify as straight. This is because the term straight describes heterosexual people, and hetero means different. Of course, unaligned nblw / nblm don't have to identify as straight, because the term was originally coined with a gender binary being considered. If a person is nblw or nblm and does not wish to be referred to as straight, then you must not call them straight. No excuses.

Straight Allies
Straight allies are straight people who support people who are not straight.

What do Straight Allies do?
Straight allies...
 * Don't make "gay jokes" (example. What do you call a man in tights? Gay!) Although it seems harmless, it makes the concept of being gay into the butt of a joke, and something that could be insulting. This could cause closeted gay friends to feel that they aren't accepted by you.
 * Assist their LGBT friends to pride, if they are asked and aren't busy. This shows solidarity, and that you're not embarrass to be by a gay person, or in a gay pride parade
 * Treat gay people and straight people the same way. If you wouldn't ask Cindy about her boyfriend every time you see her, you shouldn't ask Mary about her girlfriend every day. It can get tiring for Mary to constantly keep you updated on her relationship status.
 * Don't make homophobic comments. (example. God hates Sinners like the Gays, Science frowns upon Gays because they can't reproduce). How would you feel if the situation was reversed?
 * Speak to LGBT people about LGBT problems. Don't assume that because you're an ally you know everything there is to know about being gay - trust me, a gay person knows much more about their own experiences than you do.
 * Speak out against homophobia in conversations. This shows people that you're on their side and that you aren't afraid to speak out against prejudice.

Why are Straight Allies Important?
Without Straight Allies helping us, the LGBT/MOGAI community would struggle to get as much attention as we do in today's society. Without people letting us know that its seen as OK to be gay, many people would still be in the closet, without anybody to turn to.
