The TRAs like to tell us that cis is an acceptable word to call people and I have often heard it used as similar to straight or heathen. I have no problem being called straight or heterosexual as everybody has a sexuality and I am a woman attracted to men. Heathen is a term used by some Christians to describe people that don't believe in Christianity. I joke that I am a heathen due to my Catholic education, it's just so batcrap crazy that I became an atheist in primary school.
Cis is not an equivalent as it presupposes a belief in gender. Trans is people who believe they have a gender identity which isn't the same as their sex and cis is people who have a gender identity that matches their sex. Genderists can't have that much faith in their belief system as they don't allow people to not believe. Religions have terms for unbelievers as they are so confident in their belief that it doesn't crumble if someone says gods don't exist. Genderists know that their system only works if everyone believes in it because it's so flimsy.
Queer being reclaimed as a word means that it's being used widely to replace gay/lesbian/homosexual. The people doing this say it's a positive thing due to the previous negative connotation of the term.
Let's compare this to the reclaiming of the n word. Some black people are reclaiming the word but it's widely understood to only be acceptable to be used by black people either by themselves or others who are happy to be called it by their peers. It's totally unacceptable for anyone who isn't black to use the term, even if the black person being referred to uses it about themselves.
Queer is not only used by straight people to describe gay men, lesbians and bisexual people, it's used whether the LGB person is happy with the term or finds it deeply homophobic.
Black people are not calling all black people the n word and are not setting up groups for n*rs. The black people murdered by the KKK are not being retrospectively called n words. Queer activists however are very much doing the same to LGB people whether they like it or not.
Many large companies have LGBTQ groups and they often provide information about how allies can support their colleagues. They will use the term queer quite happily as if it's a non controversial term. Can you imagine if say, the NHS sent out something to employees to let them know how to support their n word colleagues?
That was a lot longer than I expected, sorry.
The way the words cis and queer are used is nothing to do with how activists say they compare with other terms. It's just more lies from the intolerant TRAs
