While there are several different meanings of the word "slur," the meaning that will be discussed on this page is that of words which are used in a derogatory and bigoted context. More specifically in the context of this site, this will be derogatory and bigoted words that are used towards queer people.
Chances are that if you are transgender, you have been called a slur at some point. Perhaps on the internet. Perhaps in person. Perhaps both. It is very difficult to avoid transphobia of any kind, especially that what which permeates language.
While traditionally used alongside physical acts of violence, many transphobes will argue that slurs are not themselves violent. In the United States, slurs are argued to be protected under the first amendment, which grants freedom of speech. The schematics of this can be debated, but at the very bare minimum, these are not words which are used in very polite company.
One of the easiest things that you can do as an ally of the transgender community is to call out those who use these words. Only use a gendered term to refer to a person if that particular person desires to be called that particular word.
Unfortunately, virtually every single word with a gendered connotation has been used as a slur at some point. Any and every gendered word that can be used as a neutral or positive self-descriptor can be, has been, and will be used in a derogatory way towards another person. This is inescapable so long as those who follow transphobic ideologies (such as gender critical). This list will include words that have purely (or primarily) been used in a derogatory context.
There are some slurs on this list that are considered "reclaimed." Reclamation of a slur happens when the group of people who are primarily targeted by the slur decide that they would like to use that word for themselves with a positive or neutral connotation.
The general rule of thumb that comes along with slurs is that once you are aware that it is a slur, you shouldn't be using it. If you for some reason feel the urge to use it, at the very least look into the history of that word so that you are aware of the impact that the word you saying can have on the mental health and well-being of the people you are trying to use it on.
Many slurs are used often in porn, reducing the people they are referring to down to nothing more than sex objects to appeal to chasers. Many of these words appear as entire categories on pornographic websites (both with in animated porn such as hentai, and that which contains real people). Unfortunately, this is the only exposure that many people have to the transgender community. Someone who views transgender people as nothing more than a porn topic are rarely interested in seeking out more information on the community. It is disheartening to be a transgender person and having to deal with someone shouting a fetishistic slur at you, or accusing you of only being transgender for the purposes of tricking straight people into having sex with you (a common porn trope).
Disclaimer - This list of slurs includes the primary target of their usage, though bigots aren't exactly making sure that they are always being 100% accurate regarding the identities of their targets.
